A hollow double concave lens is made of very thin transparent material. It can be filled with air or either of two liquids L_1 or L_2 having refractive indices mu_1 and mu_2 respectively (mu_2gtmu_1gt1) . The lens will deverge a parallel beam of light if it is filled with

As Fig. shows, S_(1) and S_(2) , are spring balances. Block A is hanging from spring balance S_(1) and immersed in liquid L which is contained in beaker B . The mass of beaker B is 1 kg and mass of liquid L is 1.5 kg . Balances S_(1) and S_(2) reads 2.5 kg and 7.5 kg , respectively. What will be the readings of S_(1) and S_(2) when block A is pulled up out of the liquid. Find the reading of S_(1) and S_(2)?
