A point charge of 5 C is located at the origin ... - SS2 Physics Electromagnetism Question
A point charge of +5 μC is located at the origin. What is the electric potential at a point 2 metres away from the charge? (Assume vacuum permittivity is ε0 = 8.85 x 10-12 C2/N m2)
The electric potential due to a point charge is given by: V = (k x |q|) / r
V = (9 x 109 N m2/C2 x 5 x 10-6 C) / 2 m = 9 x 106 V
