Two blocks A and With mass 4 kg and 6 kg...

Two blocks A and With mass 4 kg and 6 kg respectively are connected by a stretched spiring of negligible mass as in figure. When the two blocks are released simultaneously the initial acceleration of B is `1.5 m//s^(2)` westward. The acceleration of A is :

A

`1 m//s^(2)` westward

B

`2.25 m//s^(2)` eastward

C

`1 m//s^(2)` eastwards

D

`2.75 m//s^(2)` westwards

Text Solution

Verified by Experts

The correct Answer is:
B

F=kx=6x1.5=9
Now kx=9=4a
a=2.25
