Two blocks A and B of masses 1.5 kg and i.5 kg, respectively are connected by a massless inextensible string passing over a frictionles pulley as shown in the figure. Block A is lifted until block B touches the ground and then block B touches the ground and then block A is released. the initial height of block A is 80 cm when block B just touches the ground. the maximum height reached by block B from the ground after the block A falls on the ground is
