Question

In the figure shown C is a fixed wedge on horizontal surface Blocks A and B are of masses m and 2m respectively are kept as shown in figure They can slide along the incline plane smoothly The pulley and string are massless The inclined planes are very long A and B are released from rest 2 seconds after the release B is caught for a moment and released again Then Take 30 and g 10m s Choose the correct option s 0 30 C B A the speed of A just before the instant when the string becomes tight again will be 10 3 m s B the speed of A just before the instant when the string becomes tight again will be zero C the speed of A just after the instant when the string becomes tight again will be 20 9 m s D the speed of A just after the instant when the string becomes tight again will be 10 3 m s
