A plank is floating in a liquid as shown, Fraction f of its volume is immersed. Choose the correct options

A

If the system is taken to a place where atmospheric pressure is more. F will increase

B

In above condition f will remain unchanged

C

If temperature is increasesd and expansion of only liquid is considered f will increases

D

If temperature is increased and expansion of only plank is considered f will decrease

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
Fraction of volume immeresed,
`f=(rho_s)/(rho_l)`
This fraction is independent of atmospheric pressure, with increase in temperature `rho_(s)` and `rho_(l)` both will decrease.
