Electric charge is uniformly distributed inside a nonconductingsphere of radius 0.30m. the electric field at a point p, which is0.50m from the center of the sphere, is 17,000 N/C and is directedradially outward. What is the maximum magnitude of the electricfield due to this sphere?

A) 25,000 N/C

B) 42,000 N/C

C) 36,000 N/C

D) 47,000 N/C

E) 30,000 N/C

I know the answer is D (according to my professor), but cansomeone please explain to me why and what steps it takes to getthat??
