A cubical block of mass m 1 kg is placed on a smooth horizontal surface as shown Its centre is tied to a massless and inextensible string of length 10 m and other end of the string is connected to ball of same mass Ball is released from the position shown It falls under gravity and then string becomes taut The kinetic energy of block and ball just after string is taut are KE and KE respectively then g 9 8 m s 1 30
