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.

Question

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., The balance A will read more than 2 kg, The balance B will read less than 5 kg, The balance A will read less than 2 kg and B will read more than 5 kg, The balance A will read more than 2 kg and B will read less than 5 kg

MARKS App · Accepted Answer

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 .
