Two blocks of masses 5 kg and 10 kg are connected to a pulley as shown. What will be their acceleration if the pulley is set free ? (g = acceleration due to gravity)



Important Questions on Laws of Motion


Three blocks of masses m1, m2 and m3 are connected by massless strings as shown in the figure on a frictionless table. They are pulled with a force of 40 N. If m1 = 10 kg, m2 = 6 kg and m3 = 4 kg, then tension T2 will be :-

Three masses M1, M2 and M3 are lying o n a frictionless table. The masses are connected by massless threads as shown. The mass M3 is pulled by a constant force F as shown. The tension in the thread between masses M2 and M3 is :-



Three blocks are connected as shown in fig. on a horizontal frictionless table if m1 = 1 kg, m2 = 8 kg, m3 = 27 kg and T3 = 36N, T2 will be :-

Two bodies of masses 5 kg and 4 kg are arranged in two different ways as shown in fig. (A) and (B). If the pulleys and the table are perfectly smooth, the acceleration of the 5 kg body in case (A) and (B) are respectively :-
