Two identical balls `A` and `B`. each of mass `2 kg` and radius `R`, are suspended vertically from inextensible strings as shown in Fig. The third ball `C` of mass `1 kg` and radius `r=(sqrt(2)-1)R` falls and hits `A` and `B` symmetrically with `10 m//s`. Speed of both `A` and `B` just after the collision is `3 m//s`.

Impulse provided by each sting during collision is

A

`6sqrt(2)Ns`

B

`12Ns`

C

`3sqrt(2)Ns`

D

`6Ns`

Text Solution

Verified by Experts

In the figure shown, the two identical balls of mass M and radius R each, are placed in contact with each other on the frictionless horizontal surface. The third ball of mass M and radius (R )/(2') is coming down vertically and has a velocity =upsilon_(0) when it simultaneously hits the two balls and itself comes to rest. Then, each of the two bigger balls will move after collision with a speed equal to :
