SATHEE: Electrostatics Question 153

Electrostatics Question 153

Question: Two metallic spheres of radii $1 c m$ and $2 c m$ are given charges $10^{- 2} C$ and $5 \times 10^{- 2} C$ respectively. If they are connected by a conducting wire, the final charge on the smaller sphere is [CBSE PMT 1995]

Options:

A) $3 \times 10^{- 2} C$

B) $1 \times 10^{- 2} C$

C) $4 \times 10^{- 2} C$

D) $2 \times 10^{- 2} C$

Show Answer

Answer:

Correct Answer: D

Solution:

$Q_{1} = 10^{- 2} C$ , $Q_{2} = 5 \times 10^{- 2} C$

Total charge of the system Q = 6x10-6 C Charge on small sphere $Q_{1}^{'} = \frac{Q r_{1}}{r_{1} + r_{2}} = \frac{6 \times 10^{- 2} \times 1}{1 + 2} = 2 \times 10^{- 2} C$
