Question

The number of electrons constituting 10C of charge is?

• A.
  $6.25\times {10}^{24}$
• B.
  
  $6.25\times {10}^{19}$
• C.
  $6.0\times {10}^{25}$
• D.
  $6.0\times {10}^{19}$

Answer 1

The correct option is B


$6.25\times {10}^{19}$
Number of electrons in 10C charge is $\frac{10}{1.6\times {10}^{-19}}=6.25\times {10}^{19}$
