Choose the correct answer 1 The bulk modulus of rubber is 9 8 x 108 N m To what depth should a rubber ball be taken in a lake so its volume is decreased by 0 1 Pw 1000 kg m g 9 8 m s 1 25 m 2 100 m 3 200 m 2 A metalic rod of length L and cross sectional area A is made of material of young s modatus Y If the rod is elongated by an amount then the work done in elongation is proportional to 1 e X3 12 4 p2 By inserting a capillary tube upto depth in water the water rises to a height h If the lower end of the capillary tube is closed inside water and capillary is taken out and closed end opened The length of water remain in the tube is Here h 2 1 e 1 1 Zero 3 2 h 4 h A body floats in water with 40 of its volume outside water When same body floats in an oil 60 of its volume remains outside the oil The relative density of oil is 1 0 9 2 1 0 3 1 2 4 1 5 5 A solid sphere falls with a teminal velocity of 10 cm sec in the earth s gravitational field If it is released from rest in a gravity free space then terminal velocity will be heverr tamin 1 Equal to 10 cm sec 2 More than 10 cm sec 3 Equal to 20 cm sec 4 Zero 4 2 h
