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

Options:

Answer:

Solution:

In the first case, m will remain at rest.

$a_{M} = \frac{F}{M}$

In the second case, both will accelerate :

$a_{m} = a_{M} = \frac{F}{M + m}$

In the second case, force on $m = ma_{m} = \frac{mF}{M + m}$
