PHYS 2092 Lab 2: Electric Potential and Field Mapping ANSWER SHEET Student Name: DJEMIRATOU SAWADOGO Response Table 2.1 Type of Charge Configuration (Yes or No) Reasons (Explain briefly) Two Like Charges E = 0 N/C? YES Zero field location is equally spaced between both like charges Multiple E = 0? NO Only 1 zero field was located because the zero-field location is equally spaced between the 2 charges Two Opposite Charges E = 0 N/C? NO NO zero field Multiple E = 0? NO Because not one zero field was located Four Charges E = 0 N/C? YES Zero field location is equally spaced between all 4 charges Multiple E = 0? NO Only 1 zero field was located because the zero-field location is equally spaced between all 4 charges Response Table 2.2 Type of Charge Configuration (Yes or No) Reasons (Explain briefly) Two Like Charges V = 0 volts? NO No zero volts Multiple V = 0? NO Because not one zero volt was located Multiple V ≠ 0? Two Opposite Charges V = 0 volts? YES Zero volts can be in the area between the two charges where the electric potential of each charge interact Multiple V = 0? YES 3 total locations with V=0 were found on the map during this experiment Multiple V ≠ 0? NO The zero value of V depends on the

charge. Four Charges V = 0 volts? YES Zero volts can be in the area between the two charges where the electric potential of each charge interact Multiple V = 0? YES 5 total locations for zero volts. Multiple V ≠ 0? NO Become 0 or not equal to 0 based on charge Screenshots (insert any/all screenshots here, appropriately labeled) Figure 1: picture of an electric field with E=0 N/C for two like charges

Figure 4: Pictures of an electric field with V=0 for four charges Conclusions  What can you say about the overall directions of the Electric field configuration in the “Two Like Charges” scenario? The overall direction of the electric field configuration is radially outward from each of the like charges, away from them.  What did you conclude about the zero-point voltage in the “Two Like Charges” scenario? The zero-point voltage (electric potential) is not zero; it is not mentioned as zero in the response table.  What did you conclude about the non-zero voltages in the “Two Like Charges” scenario? Non-zero voltages exist in this scenario.  What can you say about the overall directions of the Electric field configuration in the “Two Opposite Charges” scenario?

In the "Two Opposite Charges" scenario, the electric field configuration is characterized by field lines that originate from the positive charge and terminate on the negative charge. The electric field lines point radially outward from the positive charge and radially inward toward the negative charge. This results in a dipole-like configuration with field lines extending from one charge to the other.  What did you conclude about the zero-point voltage in the “Two Opposite Charges” scenario? In the "Two Opposite Charges" scenario, the zero-point voltage, also known as the electric potential or voltage at a reference point (often taken to be at infinity), is typically defined as zero. This is a common convention in electrostatics to simplify calculations and analysis.  What did you conclude about the non-zero voltages in the “Two Opposite Charges” scenario? In the "Two Opposite Charges" scenario, non-zero voltages will exist at points in the electric field between the two charges. The electric potential or voltage at any point in the field can be calculated using the formula:  What can you say about the overall directions of the Electric field configuration in the “Four Charges” scenario? In the "Four Charges" scenario, the overall directions of the electric field configuration will depend on the specific arrangement of the charges. Without knowing the exact positions and magnitudes of the charges, it is not possible to provide a general answer. The electric field lines will follow the same principles of starting from positive charges and ending on negative charges or extending infinitely for unbound charges.  What did you conclude about the zero-point voltage in the “Four Charges” scenario? In the "Four Charges" scenario, the zero-point voltage is typically defined as zero, following the same convention as in the "Two Opposite Charges" scenario. It's often convenient to choose a reference point where the voltage is zero.  What did you conclude about the non-zero voltages in the “Four Charges” scenario? In the "Four Charges" scenario, non-zero voltages exist at points in space due to the presence of the charges. The voltages at different points will depend on the arrangement and magnitudes of the charges. Some points may have positive voltage, some negative, and some zero, depending on their distances and positions relative to the charges. The voltages will also depend on the choice of reference point where zero voltage is defined.
