A ring of mass m can slide along a fixed rough vertical rod as shown The ring is connected by a spring of constant K where 2R is the natural length of spring The other end of spring is fixed to the ground at point A at a horizontal distance of 2R from the base of the rod 4mg R 3R If the ring is released from a height of and it reaches the ground with a speed of 3gR 2 The coefficient friction between the rod and ring is 1 A 413 n2 wwww 2R 1 B 4 3 2 n2 3R 2 1 C 813 4 02
