A block is partially immeresed in a liquid and the vessel is accelerating upwards with an acceleration 'a'. The block is observed by two observers `O_1` and `O_2`, one at rest and the other accelerating with an acceleration 'a' upward. The total buoyant force on the block is :

A

same for `O_(1)` and `O_(2)`

B

greater for `O_(1)` then `O_(2)`

C

greater for `O_(2)` then `O_(1)`

D

data is not sufficient

Text Solution

Verified by Experts

The correct Answer is:
A
Buyont force `=F_(b)=V_("sub").rho_(l).g`
Where `v_("sub"), rho_(l)` and g all are same w.r.t `O_(1)` and `O_(2)`
Hence (1)
