A) \[6.25\times {{10}^{27}}\]
B) \[1.6\times {{10}^{19}}\]
C) \[6.25\times {{10}^{28}}\]
D) \[6.25\times {{10}^{9}}\]
Correct Answer: D
Solution :
: Charge on the body is q = ne \[\therefore \] No. of electrons present on the body is \[n=\frac{q}{e}=\frac{1\times {{10}^{-9}}C}{1.6\times {{10}^{-19}}C}=6.25\times {{10}^{9}}\]You need to login to perform this action.
