Question
A large nonconducting sheet M is given a uniform charge density. Two uncharged small metal spheres A and B are placed near the sheet as shown in figure.
Options
A.M attracts A
B.A attracts B
C.M attracts B
D.B attracts A
Solution
(i) Figure after induction is :
(ii) Field due to M is uniform ∴ Force between M and A = 0.
Also, force between M and B = 0
& A and B attract each other due to induction.
(ii) Field due to M is uniform ∴ Force between M and A = 0.
Also, force between M and B = 0
& A and B attract each other due to induction.
