a moving sphere p collides with another sphere q at rest,if the collision takes place along the line joining their centre of mass such that their total k.e. is conserved and the fraction of k.e. transferred by the colliding particle is 8/9,the mass p and the mass q bear the ratio of

Question

vikas askiitian expert · Answer

let the mass of particle p be Mp and the mass of other particle q be Mq

let initial momentam of particle Pi

aplying conservation of momentam

Pi + o = Pf + Qf ......1 ( Pf,Qf are the momentam of P,q after collision)

by using p^2/2m = KE EQ 1 becomes

sqrt{(KE)pi. Mp} = sqrt{(KE)pf. Mp} + sqrt{(KE)qf.Mq}..........2

now applying conservation of total kinetic energy

(kinetic energy initially) (KE)pi +0 = (kE)pf +(kE)qf (final kinetic energy of p,q)

from the given data that 8/9 (kinetic energy of particle p) is transferred to particle q so now KE of p now is 1/9of initial

so (KE)pf =1/9 (kE)pi..........3

(KE)qf =8/9 (KE)pi..........4

putting values from 3,4 in eq 2

Mp/Mq =2

approve my ans if u like
