`_83^212Bi` decays as per following equation.
`_83^212Birarr_82^208Ti+_2^4He`
The kinetic energy of `alpha`-particle emitted is 6.802 MeV. Calculate the kinetic energy of Ti recoil atoms.

Text Solution

Verified by Experts

The correct Answer is:
A, C

From momentum of conservation,
`p_1=p_2`
`:.` sqrt(2K_1m1)=sqrt(2K_2m_2)`
`:.` `K_2=(K_1m_1)/(m_2)=((6.802)(4))/(208)`
`=0.1308 MeV`
