Positive charge Q is distributed uniformly throughout an insulatingsphere of radius R,
centered at the origin. A positive point charge Q is placed at x =2R on the x axis. The
magnitude of the electric field at x = R/2 on the x axis is:
A) 2
Q 4p ?0 R
B) 2
0 Q 8p ? R
C) 2
0 7Q 18p ? R
D) 2
0 11Q 18p ? R
E) none of these
