Question 2 An isolated solid spherical metal ball of radius R has charge Q 1 uniformly distributed over its surface. A charge, Q 2 , is introduced, a distance 2R from the center of the sphere. The ectric field at the center of the sphere is: :[k=1/(4 electric field at the center of the sphere is: :[k=1/(4   A) k*Q 2 /4R 2 B) k*Q 2 /R 2 C) 0 D) k(Q +Q )/R 2 R Q 1 1 2 E) k (Q 1 +Q 2 )/4R 2 2R Q 2
