Electrostatics Question 25

Question: The radius of two metallic spheres A and B are r1 and r2 respectively (r1>r2) . They are connected by a thin wire and the system is given a certain charge. The charge will be greater

Options:

A) On the surface of the sphere B

B) On the surface of the sphere A

C) Equal on both

D) Zero on both

Show Answer

Answer:

Correct Answer: B

Solution:

After connection of wire, potential becomes equal Q1r1=Q2r2

therefore Q1Q2=r1r2 when r1 > r2, then Q1>Q2
