If block B moves towards right with acceleration b, find the net acceleration of block A.

A

`bhat(i)+4bhat(j)`

B

`bhat(i)+bhat(j)`

C

`bhat(i)+2bhat(j)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A

Acceleration of A in horizontal direction= the acceleration of B=b rightwards
Acceleration of A in vertical direction =the acceleration of A with respect to b in upwards direction `=a=4b`.
Hence, net acceleration of `A=b hat(i) + 4b hat(j)`.

Two smooth block are placed at a smooth corner as shown in fig. Both the bloks are having mass m. We apply a force F on the block m. Block A presses block B in the normal direction, due to which pressing force on vertical wall will increase, and pressing force on the horizontal wall decreases, as we increases F(theta = 37^(@) with horizontal). As soon as the pressing force on the horizontal wall by block B become zero, it will lose contact with ground. If the value of F further increases, block B will accelerate in the upward direction and simulaneously block A will towards right. If the acceleration of block A is a rightwards, then the acceleration of block B will be
