Correct Answer: C
Solution :
(c) 198 years The charge given out in one second \[=1.6\times {{10}^{-19}}C\times {{10}^{9}}=1.6\times {{10}^{-10}}C\] Time required to accumulate a charge of 1 C \[=\frac{1}{1.6\times {{10}^{-10}}}=6.25\times {{10}^{9}}s=198\]yearsYou need to login to perform this action.
