Question

Given two particles with Q = 1.70-C charges as shown in the figure below and a particle with charge q = 1.22 10-18 C at the origin. (Note: Assume a reference level of potential V = 0 at r = .)

(a) What is the net force exerted by the two 1.70-C charges on the charge q?_________N

(b) What is the electric field at the origin due to the two 1.70-C particles? ___________N/C

(c) What is the electrical potential at the origin due to the two 1.70-C particles? ____________kV

Explanation / Answer

a.

Fnet=KQq/ x^2 - KQq/ x^2 -----------1

As Qq & X VALUES ARE same

Fnet =0 on the charge q.

b.

Enet is also Zero.

Enet=Eby Q - E by Q =0

c.

Vnet=KQq/ x + KQq/ x

Vnet=2KQq/ x = 2 *9*10^9*1.70*10^-6*1.22*10^-18 / 0.8

Vnet=46.66*10^-18 KV
