The distance of closest approach of ana-particle is fired at a nucleus with momentum p is r0. When the a-particles are fired at the same nucleus with momentum 5p, the distance of closest approach will be –

A

5r0

B

25r0

C

15\frac{1}{5}r0

D

125\frac{1}{25}0

Answer

125\frac{1}{25}0

Explanation

Solution

r0 =2kZe2E\frac{2kZe^{2}}{E}, E =P22m\frac{P^{2}}{2m}
