The spring balance $A$ reads $2 kg$ with a block of mass $m$ suspended from it. A balance $B$ reads $5 kg$ when a beaker with liquid is put on the pan of the balance. The two balances are now so arranged that the hanging mass is inside the liquid in a beaker as shown in the figure.

Options:

Answer:

Solution:

The effective weight of the block in the liquid will become less than $2 kg$ due to buoyancy of liquid. As a result of which $A$ will read less than $2 kg$ .

As the body immersed in liquid has some effective weight acting downwards so the reading of $B$ will be more than $5 kg$ .
