Question

A large non-conducting sheet M is given a uniform charge density. Two uncharged small metal rods A and B are placed near the sheet as shown in the figure (30-Q4).
(a) M attracts A.
(b) M attracts B.
(c) A attracts B.
(d) B attracts A.

Answer 1

(a) M attracts A.
(b) M attracts B.
(c) A attracts B.
(d) B attracts A.



Since the non-conducting sheet M is given a uniform charge, it induces a charge in the metal rod A, which further induces a charge in the metal rod B, as shown in the figure. Hence, all the options are correct.
