Homework Statement
Electric charge is uniformly distributed inside a nonconducting sphere of radius 0.30 m. The electric field at a point P, which is 0.50 m from the center of the sphere, is 15,000 N/C and is directed radially outward. At what distance from the center of the sphere does the electric field have the same magnitude as it has at P?
Homework Equations
E = KQ * (1/r^2)
The Attempt at a Solution
So I tried using the equation E = KQ * (1/r^2) but I'm not given a charge. What should I do? Is finding the charge of P helpful? Does the charge not matter in this case and I'm just using the wrong equation?
