A) \[3.2\,\times \,{{10}^{-14}}N\]
B) \[4N\]
C) \[3.2\,\times \,{{10}^{-12}}N\]
D) None of these
Correct Answer: A
Solution :
\[E=\frac{V}{r}\]and\[F=qE\] \[F=\frac{q}{r}.V\] \[F=\frac{e}{r}.V=\frac{1.6\times {{10}^{-19}}\times {{10}^{4}}}{5\times {{10}^{2}}}\] \[=3.2\times {{10}^{-14}}N\]You need to login to perform this action.
