Type: MCQ-numerical-Medium

An alpha particle of energy 5 MeV is scattered through 180° by a fixed uranium nucleus. The distance of closest approach is of the order of

A

1 A

B

10⁻¹⁰ cm

C

10⁻⁴ m

D

10⁻¹⁵ cm

Correct Answer

Option B

Detailed Explanation

The distance of closest approach is calculated using the formula for scattering, which involves the energy of the alpha particle and the charge of the nucleus. For a 5 MeV alpha particle, this distance is approximately 10⁻¹⁰ cm.
