A positively charged glass rod is brought near uncharged metal sphere, which is mounted on an insulated stand. If the glass rod is removed, the net charge on the metal sphere is
A
negative charge
B
zero
C
D
positive charge
Text Solution
Verified by ExpertsThe correct answer is:
B
The positive charged rod induces negative charge on the side of the sphere closer to the rod and equal positive charge on the other side of the sphere. When the rod is withdrawn the negative charge neutralise the equal positive charge. Hence, total charge is zero.
