Block A in the figure shown here hangs by a cord from dynamometer (spring balance ) D1 and is submerged in a liquid C contained in a beaker B. The mass of the beaker is 1 kg and the mass of liquid is 1.5 kg . The readings of dynamometers D1 and D2 are2.5 kg and 7.5 kg respectively . What will be the readings of D1 and D2 if block A is pulled up out of liquid ?
