A horizontal force ''F'' produces an acceleration of `6m//s^(-2)` on a block resting on a smooth horizontal surface. The same force produces an acceleration of `3m//s^(-2)` on a second block resting on a smooth horizontal surface. If the two blocks are tied together and the same force acts, the acceleration produced will be

A

`9m//s^(-2)`

B

`2m//s^(-2)`

C

`4m//s^(-2)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
`F=ma, (1)/(a)=(1)/(a_(1))+(1)/(a_(2))`
