Question

1.13 points] A +4.0-uC charge is placed on the x axis at x +3.0 m, and a -2.0-JC charge is located on the y axis at y--1.0 m. Point A is on the y axis at y +4.0 m. Determine the electric potential t point A (relative to zero at the origin). 2 D pointsl If -30 cm,b-20 cm, 2 nC,and Q-30 nC in the figure, what is the potential difference A. B. 3. [4points) Points A (at x 4, y-2 m) and B (at x-2, y-3 m) are in a region where electric field is uniform and given by E-01-D NC. What is the potential difference r,-

Explanation / Answer

Point A( 0, 4)
q1 (3 ,0),  
q2 (0, -1)

Potential at a point at a distance r from the charge is given by V = k q/r

k is a constant = 9 x 109 , q is the charge, r is the distance

therefore, let the potential due to q1 be = V1 and due to q1 be = V2
Total potential = V1 + V2

V1 = k (4 x 10-6) / (42 + 32)1/2 = 7200V
V2 = k (-2 x 10-6) / 5 = -3600 V

Total potential = 3600 V
