Two small balls A B of masses m and 2m respectively are connected by an ideal thread of length I are kept on a smooth horizontal surface as shown The ball B is given sudden vertical velocity u as shown Ball B acquires a speed v when thread becomes vertical for the first time Acceleration due to gravity is g The value of u is such that ball A is on the verge of lifting off floor when thread is vertical Mark the INCORRECT option s 2m B a The acceleration of B at the instant when its speed is v is 3g 2 b The value of u is 3gl c The value of v is gl d The radius of curvature of path of B when its speed is y is
