A silver ingot weighing 2.1 kg is held by a string so s to be completely immersed in a liquid of relative density `0.8`. The relative density of silver is `10.5`. The tension in the string in `kg-wt` is

A

`1.6`

B

`1.94`

C

`3.1`

D

`5.25`

Text Solution

Verified by Experts

The correct Answer is:
B
Apparent weight `=V(rho-sigma)g =(M)/(rho) (rho-sigma)g = M(1-(sigma)/(rho))g = 2.1(1-(0.8)/(10.5))g = 1.94 g`
Newton `= 1.94 kg-wt`
