A block of mass m is placed in contact with one end of a smooth tube of mass M. A horizontal force F acts on the tube in each case (i) and (ii). Then,

A

`a_(m)=0 and a_(M)=(F)/(M)` in (i)

B

`a_(m) = a_(M) =(F)/(M+m)` in (i)

C

`a_(m) = a_(M) =(F)/(M+m)` in (ii)

D

Force on m is `(mF)/(M+m) in (ii)

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
In first case, m will remain at rest, `a_(M)=F//M`
In second case, both will accelerates
`a_(m)=a_(M)=F//(M+m)`
In second case, force on `m+ma_(m)=mF//(M+m)`.
