What is the momentum of photon of energy 3 MeV in k g m s − 1 ? Options: A . &nbsp9×10−21 B . &nbsp1.6×10−21 C . &nbsp3×10−28 D . &nbsp9×10−28

Answer: Option B : B p = E C = 3 × 10 6 × 1.6 × 10 − 19 3 × 10 8 = 1.6 × 10 − 21 k g m s − 1

What is the momentum of photon of energy 3 MeV in kgms−1?

Question

What is the momentum of photon of energy 3 MeV in

k g m s^{- 1}

Options:

A . 9×10−21

B . 1.6×10−21

C . 3×10−28

D . 9×10−28

Answer: Option B
:
B

p = \frac{E}{C} = \frac{3 \times 10^{6} \times 1.6 \times 10^{- 19}}{3 \times 10^{8}} = 1.6 \times 10^{- 21} k g m s^{- 1}
