A solid sphere of mass m , is suspended ...


A solid sphere of mass `m` , is suspended by means of a string in a liquid as shown.The string has some tension. Magnitudes of net force due to liquid on upper hemisphere and that on lower hemisphere are `F_(A)` and `F_(B)` respectively. Which of the following is/are true.

A

Density of material of the sphere is greater than density of liquid.

B

difference of `F_(B)` and `F_(A)` is dependent of atmospheric pressure

C

`F_(B)-F_(A)=mg`

D

`F_(B)-F_(A)=ltmg`

Text Solution

Verified by Experts

The correct Answer is:
A, D

`F_(B)+T=F_(A)+mg`
`impliesF_(B)-F_(A)=mg-TimpliesF_(B)-F_(A)ltmg`
