11.Dual Nature of Radiation and matter
easy
An electron (charge =$1.6 \times {10^{ - 19}}C$) is accelerated through a potential of $ 100,000 V$. The energy acquired by the electron is
A
$1.6 \times {10^{ - 24}}\;J$
B
$1.6 \times {10^{ - 14}}\;erg$
C
$0.53 \times {10^{ - 17}}J$
D
$1.6 \times {10^{ - 14}}J$
Solution
(d) $E = eV = 1.6 \times {10^{ – 19}} \times {10^5}$$ = 1.6 \times {10^{ – 14}}J$
