1. Electric Charges and Fields
easy
Number of electrons in one coulomb of charge will be
A
$5.46 \times {10^{29}}$
B
$6.25 \times {10^{18}}$
C
$1.6 \times {10^{ + 19}}$
D
$9 \times {10^{11}}$
(AIIMS-1999)
Solution
(b) $n = \frac{q}{e} = \frac{1}{{1.6 \times {{10}^{ – 19}}}} = 6.25 \times {10^{18}}$
