Question

The spring balance A reads 2 kg with a block m suspended from it. A balance B reads 5 kg when a beaker filled 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 as shown in figure. In this situation, The balance A will read more than 2 kg, The balance B will read more than 5 kg, The balance A will read less than 2 kg and B will read more than 5 kg, The balances A and B will read 2 kg and 5 kg respectively
