Q1 of 13 Page 134

A U-238 nucleus originally at rest decays by emitting an alpha- particle says with a velocity of v ms–1. The recoil (in ms–1) of the residual nucleus is?

(a)


(b)


(c)


(d)

Let,

Mass of Uranium nucleus = M = 238 u


Mass of α particles = m = 4 u


Recoil velocity of uranium = V


The velocity of α particle = v


According to the conservation of linear momentum






V is the recoil velocity.
