Electric Potential and Electric Potential Energy

A point charge of -6.8 µC is at the origin.
(a) What is the electric potential due to this charge at (-2.0 m, 0)?

(b) What is the electric potential to this charge at (2.0 m, -2 m)?

Solution Preview

The potential of a point charge q at distance r from it is

V = q/(4*pi*epsilon0*r)

where epsilon0 = 8.85 x 10^{-12} C^2 /(N*m^2) is the permitivity of ...
