# Find the momentum of a helium nucleus having a mass of 6 .68×10 − 27 kg that is moving at 0.200c.

To determine

The momentum of the helium nucleus.

Explanation

Given info:

The mass of the helium nucleus is 6.68Ã—10âˆ’27kg.

The speed of the helium nucleus is 0.200â€‰c.

Formula used:

Formula to find the relativistic momentum is,

â€ƒâ€ƒpâ€‰=â€‰m0v1âˆ’v2c2

Here, vis the velocity of the helium nucleus, m0is the rest mass of the helium nucleus and cis the speed of light.

Calculation:

Substituting the given values, we get,

â€ƒâ€ƒpâ€‰=â€‰6.68Ã—10âˆ’27kgÃ—0
