The momentum of a photon of energy 1 MeV in kg m/s will be –

A

5 × 10–22

B

0.33 × 106

C

7 × 10–24

D

10–22

Answer

5 × 10–22

Explanation

Solution

P = Ec\frac{E}{c}= 1×106×1.6×10−193×108\frac { 1 \times 10 ^ { 6 } \times 1.6 \times 10 ^ { - 19 } } { 3 \times 10 ^ { 8 } } kgms\frac{kgm}{s}
