If the K.E. of a particle is doubled, then its momentum will

A

Remain unchanged

B

Be doubled

C

Be quadrupled

D

Increase `sqrt2` times

Text Solution

Verified by Experts

The correct Answer is:
D
`P=sqrt(2mE) therefore P prop sqrt(E )`
i.e. if kinetic energy of a particle is doubled the its momentum will becomes `sqrt(2)` times.

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") The kinetic energy of a given body is doubled. Its momentum will
