A nucleus of $_{84} P o^{210}$ originally at rest emits an $α$ -particle with speed $v$ . What will be recoil speed of the daughter nucleus?

Answer:

Solution:

Applying principle of conservation of linear momentum,

Negative sign for recoil speed

$- (206) V_{R} + 4 V = 0$

$V_{R} = \frac{4 V}{206}$
