Homework Statement
A particle has a charge of -5.00 [itex]\mu[/itex]C. At a point near this particle, the electric field strength is 7.2 x 10^7 N/C. Determine the distance from this point to the charged particle.
q = -5.00 x 10^-6 C
E = 7.2 x 10^7 N/C
k = 8.99 x 10^9 Nm^2/C^2
Homework Equations
E = kq / r^2
The Attempt at a Solution
r = (sqrt) (8.99 x 10^9 Nm^2/C^2)(5.00 x 10^-6) / (7.2 x 10^7 N/C)
= 0.0249861073 m
