Question

In an alpha decay the kinetic energy of alpha particle is 48mev and q value of the reaction is 50mev the mass number of the mother nuvleus is

Answer 1

Answer:

Given that,

Kinetic energy K.E=48MeV

Q value Q=50

We know that,

The kinetic energy is

E=

A

A−4

×Q......(I)

Now, put the value in equation (I)

48A=(A−4)50

48A−50A=−200

2A=200

A=100

Hence, The mass number of the mother nucleus is 100
