An aluminum sphere is dipped into water ...

An aluminum sphere is dipped into water as `10^@C`. If the temperature is increased, the force of buoyancy

A

will increase

B

will decrease

C

will remain constant

D

may increase of decrease depending on the radius of the sphere

Text Solution

Verified by Experts

The correct Answer is:
B
`F_(B)=p_(0)V_(0)g`
`F_(B)(rho_(0)v_(0)(1+3alphatheta)g)/((1+gammatheta))=((1+gamma_(a)theta)/(1+gamma_(omega)theta))p_(0)V_(0)g`
`gamma_(omega)gtgamma_(a)`
`F'_(B) ltF_(B)`
