A) 1.25x1013
B) 2.5 x 1013
C) 3.75 x1013
D) None of these
Correct Answer: C
Solution :
Let n be the number of electrons in the body. \[\therefore \] \[-2\times {{10}^{-6}}=-n\times 1.6\times {{10}^{-19}}\] \[+2.5\times {{10}^{13}}\times 1.6\times {{10}^{-19}}\] \[\Rightarrow \] \[n=3.7\times {{10}^{13}}\]You need to login to perform this action.
