A block of mass 2M is connected to a ball A with the help of, an ideal spring and string as shown in the figure., System is released from rest when spring is at its natural length., For block to leave contact with ground, minimum mass of ball should be,

A block of mass m is connected with ceiling with the help of ideal spring (spring constant k) as shown in figure Mass m is released from rest when spring is at its natural length., When elongation of spring is maximum, net force on block is,
(1) mg upwards
(2) mg downwards
(3) 2 mg upwards
(4) 2 mg downwards

A block of mass m is connected with the help of an ideal string and spring in vertical plane as shown in figure If block is released from rest when spring is at its natural length, then maximum elongation of spring is

A block of mass m is connected to a ball A (mass 2M), with the help of an ideal spring and string as shown in the figure., System is released from rest when springs is at its natural length. ,Maximum mass of block (m), which can be lifted,
