Question

1_Two point charges are separated by 1.5 cm. Charge A has a charge of +2.0 uC and Charge B has a charge of +4.0 uC.

1.a_What is the value of the electric force of Charge B acting on A?

1.b_What is the direction?

2__Find the electrostatic potential difference due to point p, located at the center of the square in the diagram. Leave the answer as Q and d.

3) Four charges are placed at four corners of a square (in the previous fig), where d = 0.50 m and Q = 2.9 uC. Find the magnitude and direction of the net electric force on the Q located in the top left side. Notice the charge in the top right side is -2Q (negative).

Explanation / Answer

1)the charges are q1 = +2.0 uC and q2 = +4.0 uC

the separation between the charges is r = 1.5 cm = 1.5 x 10^-2 m

the force between the charges is

F = k x (q1q2/r^2)

where k = (1/4pi x e_o) = 9 x 10^9 Nm^2/C^2

the force between them is repulsive.
