# Problem: Suppose a point charge produces a potential of -1.7 V at a distance of 1.8 mm.What is the charge, in coulombs, of the point charge?

###### FREE Expert Solution

Electric potential;

$\overline{){\mathbf{V}}{\mathbf{=}}\frac{\mathbf{k}\mathbf{q}}{\mathbf{r}}}$

k = 9.0 × 109 N•.m2/C2

q = Vr/k = (- 1.7 × 1.8 × 10-3)/(9.0 × 109)
