A stone of mass 1 kg is lying on the floor of a train which is accelerating with `1ms^(-2)`. The net force acting on the stone is

A

zero

B

1N

C

5N

D

10N

Text Solution

Verified by Experts

The correct Answer is:
B
Here, mass of the stone, m=1kg
As the stone is lying on the floor of the train, its acceleration is same as that of train `therefore "Force acting on the stone," F=ma=(1kg)(1ms^(-2))=1N`
NOTE: Here weight of the stone is balanced by the normal reaction of hte floor.
