A) \[3\times {{10}^{-2}}C\]
B) \[1\times {{10}^{-2}}C\]
C) \[4\times {{10}^{-2}}C\]
D) \[2\times {{10}^{-2}}C\]
Correct Answer: D
Solution :
\[{{Q}_{1}}={{10}^{-2}}C\], \[{{Q}_{2}}=5\times {{10}^{-2}}C\] Total charge of the system Q = 6 ´ 10?6 C Charge on small sphere \[Q{{'}_{1}}=\frac{Q\,{{r}_{1}}}{{{r}_{1}}+{{r}_{2}}}=\frac{6\times {{10}^{-2}}\times 1}{1+2}=2\times {{10}^{-2}}C\]
