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

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

I meant to say the negative sign in the equation.
And Thank you very much. 
I was wrong about the negative sign. Relative to zero voltage at infinity, the potential at nonzero distances will be positive.
