Electric Charge Is Uniformly Distributed Inside a Nonconducting Sphere of Radius

question 1

Multiple Choice

Electric charge is uniformly distributed inside a nonconducting sphere of radius 0.30 m.

At what distance from the center of the sphere does the electric field have the same magnitude as it has at P?

• A) 0.11 m
• B) 0.13 m
• C) 0.15 m
• D) 0.17 m
• E) at no other point
