The elevator shown in figure is descending, with an acceleration of `2 m s^(-2)`. The mass of the block A is 0.5 kg and the mass of the block B is 1 kg. The force exerted by the block A on the block B is (Take g = 10`ms^(-2)`)

A

`2 N`

B

`4 N`

C

`6N`

D

`8N`

Text Solution

Verified by Experts

The correct Answer is:
B
From free body diagram of block A
` 0.5 -N = 0.5 xx 2`
` or N= 0.5 g - 0.5 xx 2`
`= 0.5 (10 -2) = 4N`
