If we double our distance from a charged particle, determine what happens to (a) the potential generated by the particle at our location; (b) the modulus of the electric field generated by the particle where we are.

Question 10 of 11 (a) In the figure a charged particle (either an electron or a proton) is moving rightward between two parallel charged plates separated by distance d = 6.10 mm. The plate potentials are V₁ = -67.0V and V₂ = -50.0 V. The particle is slowing from an initial speed of 85.0 km/s at the left plate. (a) Is the particle an electron or a proton? (b) What is its speed just as it reaches plate 2?

The electric potential from an elementary electric dipole located at the origin is given by the expression Þ(r) = p'r/(4TE,r³) where p is the electric dipole moment vector. Show that the corresponding electric field is given by the expression E = -VO = (3 p'r-hat r-hat - p)/(4tE,r³) where r-hat is the unit vector in the direction of the vector r.

We increase the magnitude of the electric field to E = 119 v/m and repeat the experiment with the same Q = +5.40C particle. Calculate the net change in the electric potential energy [Be sure the sign of your answer accurately reflects whether the particle gained or lost potential energy in moving from point (A) to point(B) in this experiment]

In the figure, the particles have charges q1 = q2 = 10.5 nC, q3 =2q4 = 12.6nC, and distance a = 4.00 cm. (a) What is the magnitude and direction ofthe net electric field at the point P? (b) How much work is required to set upthe four-charge configuration of the figure? (c) What is the potential at pointP due to the four-charge particles? (d) What is the potential energy and themagnitude and direction of the acceleration for a proton placed at point P?(e) what is the number of excess elementary charges for each particle?
