easy
ફોટોનની ઊર્જા $10\,eV$ છે. તો તેનું વેગમાન $.............$
A
$5.33 \times 10^{-23}\,kg\,m / s$
B
$5.33 \times 10^{-25}\, kg\, m / s$
C
$5.33 \times 10^{-29}\, kg\, m / s$
D
$5.33 \times 10^{-27}\, kg\, m / s$
Solution
(d)
Momentum of a photon $\propto \frac{E}{c}$
$=5.33 \times 10^{-27}\,kg\,ms ^{-1}$
