A box 'A' is lying on the horizontal floor the compartment of a train running along horizontal ralls from left to right. At time 't', it decelerates. Then the resultant contact force R by the floor on the box is given best by :

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C

Acceleration of trail will be from right to left.
`rArr` Pseudo force will act on the box from left to right therefore friction will act from right to left.
