Question

17. Potential due to a point charge: What is the electric potential 17.0 cm from a 3.50 μC point charge?

Answer 1

V = -k Q/R

k is the Coulomb's Law constant
= 8.99*10^9 N*m^2/C^2
Q = 3.50*10^-6 C
R = 0.17 m

Solve for V, which will be in J/C units

Answer 2

So because of the negative sign in the question would the answer end up being negative?

Answer 3

I meant to say the negative sign in the equation.
And Thank you very much.

Answer 4

I was wrong about the negative sign. Relative to zero voltage at infinity, the potential at nonzero distances will be positive.
