Question
1. A particle has charge -3.00 nC. A. Find the magnitude and direction of the electric field due to this particle at a point 0.250m directly above it. B. At what distance from this particle does its electric field have a magnitude of 12.0 N/C?
Enety Ø = tan-1 = 50.98°North of West Enetx ACTIVITY 2. ELECTRIC FIELD Direction: Solve the following problems completely and neatly. Write your answer on the answer sheet. 1. A particle has charge -3.00nC. A. Find the magnitucle and direction of the electric field due to this particle at a point 0.250m directly above it. B. At what distance from this particle does its electric field have a magnitude of 12.0 N/C? 2. Point charge q = -5.00 nC at the origin and point charge q2= +3.00 nC is on the x-axis at x = 3.00 cm. Point P is on the y-axis at y = 4.00 cm. A. Calculate the electric fields E, andE, at point P due to the charges q, and q2. Express your results in terms of unit vectors. B. Use the results of part A to obtain the resultant field at P, expressed in unit vector form. 3. A +2.00 nC point charge is at the origin, and a second -5.00 nC point charge is on the x-axis at x = 0.800 m. A. Find the electric field (magnitude and direction) at each of the following points on the x-axis: i. ii. x= 1.20 m X 0.200 m iii. x = -0.200 m В. Find the net electric force that the two charges would exert on the electron placed at each point in part A.
