Solution

The correct option is A 37.12N
Let ρs, ρl be the density of silver and liquid.
Let ms and Vs be the mass and volume of the silver block.

In equilibrium, the sum of tension and buoyant force is equal to the weight of the silver block. Hence
T+Vs×ρl×g=Vs×ρs×g
T=(ρsρl)Vsg=(ρsρl)msρsg
T=ρsρlρsmsg
T=100.72104×10=37.12N
