Two bodies of masses 3 m and m have their K.Einh 27:1 then the ratio of the momentum is

A

`9:1`

B

`1:9`

C

`1:3sqrt3`

D

`1:1`

Text Solution

Verified by Experts

The correct Answer is:
A
`P=sqrt(2mK.E)`
`therefore(P_1)/(P_2)=sqrt((2m_1K.E_1)/(2m_2K.K_2))=sqrt((2xx3mxx27)/(2xxmxx1))=sqrt((81)/(1))=9/1`

Relation between kinetic energy and momentum Let us consider a body of mass 'm' having a velocity 'v', then momentum of the body P = mass xx velocity P = m xx v rArr v = (P)/(m) " "...(1) From definition, kinetic energy (K.E) of the body K.E = (1)/(2) mv^(2)" "...(2) Now putting the value of (1) in (2) we have K.E = (1)/(2)m ((P)/(m))^(2) K.E. = (1)/(2)m (P^(2))/(m^(2)) = (1)/(2) (P^(2))/(m) = (P^(2))/(2m)" "...(3) Thus we can write P^(2) = 2m xx K.E rArr P = sqrt(2m xx K.E) Thus momentum = sqrt(2 xx "mass" xx "kinetic energy") Two bodies masses 1 kg and 4 kg having equal kinetic energies.
