V =   V  

Part C

What is the electric potential at (3.0m, - 3.0m)?

Express your answer using two significant figures.

V =   V  

Explanation / Answer

Electric potential is given by - k*q/r

Electric potential at (3.0 m, 0) = - (8.9* 10^9 * 7.1 * 10^-6 )/ 3 volt
Electric potential at (3.0 m, 0) = - 21.1 kV

Electric potential at (-3.0 m, 0) = - (8.9* 10^9 * 7.1 * 10^-6 )/ 3 volt
Electric potential at (-3.0 m, 0) = - 21.1 kV

Electric potential at (3.0 m, -3.0 m) = -(8.9* 10^9 * 7.1 * 10^-6 )/ 3*sqrt(2) volt
Electric potential at (3.0 m, -3.0 m) = -14.9 kV
