Question

The momentum of an electron of wavelength 100 Å is

A

6.6 × 10²⁶ kg ms^–1

B

6.6 × 10^–23 kg ms^–1

C

6.6 × 10^–26 kg ms^–1

D

6.6 × 10²³ kg ms^–1

Answer

6.6 × 10^–26 kg ms^–1

Explanation

Solution

p = $\frac { 6.63 \times 10 ^ { - 34 } } { 10 ^ { - 8 } }$

= 6.63 × 10^–26 kg-m /s
