A) \[7.3\times {{10}^{-3}}C\]
B) \[3.7\times {{10}^{-6}}C\]
C) \[7.3\times {{10}^{-6}}C\]
D) \[3.7\times {{10}^{-3}}C\]
Correct Answer: D
Solution :
[d] Here, \[D=2r=4.4m,or=f=2.2m\] \[\sigma =60\mu C{{m}^{-2}}\] Charge on the sphere, \[q=\sigma \times 4\pi {{r}^{2}}\] \[=60\times {{10}^{-6}}\times 4\times \frac{22}{7}\times {{\left( 2.2 \right)}^{2}}=3.7\times {{10}^{-3}}C\]You need to login to perform this action.
