The net electric charge of particle A is 4 nC and the net electric charge of par

Question

The net electric charge of particle A is 4 nC and the net electric charge of particle B is 5 nC. What is the electric potential (in V) of this system at the position A system consists of three point particles, A, B, and C, as shown in the figure. The net electric charge of particle A is -3 nC. the net electric charge of particle B is +4 nC, and the net electric charge of particle C is -5 nC. What is the electric potential (in V) of this system at the position P? What is the electric potential a distance z = 3 m directly above the center of a uniformly charged thin square?

Explanation / Answer

3)

qA = -3 nC

qB = 4 nC

qC = - 5 nC

as the potential due to charge q at distance d is given as

V = k * q/d

for the total potential at point P , we will add potential due to all charges present

hence ,

VP = VA + VB + VC

VP = k * qA/sqrt(3^2 + 4^2) + k * qB/srqt(3^2 + 4^2) + k * qC/3

VP = 9 *10^9 * 10^-9 * (-3/5 + 4/5 - 5/3)

VP = -13.2 V

the potential at point P is -13.2 V
