A vessel filled with water is kept on a weighing pan and the scale adjusted to zero. A block of mass 10 kg is suspended by a massless spring of spring constant `k=100N//m`. This block is submerged inside into the water in the vessel such that elongation i spring is `x=10cm`. What is the reading of the scale?

100 N

10 N

110 N

90 N

Text Solution

Verified by Experts

The correct Answer is:

`mg=kx+F_(B)`, Bouyancy force force on the block is equal to force on vessel i.e., `=` reading of scale.
