Two persons of mass `m_(1)` and `m_(2)` are standing at the two ends A and B respectively, of a trolley of mass M as shown.

Choose the incorrect statement, if `m_(1) = m_(2) = m` and both the persons jump one by one, then:

A

the centre of mass of the system remains stationary

B

the final velocity of the trolley is in the direction of the person who jumps first

C

the final velocity of the trolley is `((mu_("rel"))/(M+m)-(mu_("rel"))/(M+2m))`

D

none of these
