Two masses rest on smooth surface as shown in the figure. Force exerted by `P` on `Q` is.

A

`1.5N`

B

`1N`

C

`2N`

D

`3N`

Text Solution

Verified by Experts

The correct Answer is:
B
Acceleration of the system,
`a=(F)/(m_(1)+m_(2))=(3)/((2+1))`
`=(3)/(3)=1ms^(-2)`
Force exerted by block `P` on block `Q` is
`1xx1=1N`
