Two blocks A and B of masses 3 m and m respectively are connected by a massless and inextensible string. The whole system is suspended by a massless spring as shown in figure. The magnitudes of acceleration of A and B immediately after the string is cut, are respectively :-    [2017]A: B: g, gC: D:

A block of mass 10 kg is suspended by an inextensible string passing over a smooth frictionless pulley. If the mass is pulled up at an acceleration of 1 m/s², calculate the tension in the string.

Two wooden blocks of masses 5 kg and 3 kg are connected by a massless rope. The 5 kg block is pulled by a horizontal force of 40 N.[All floors are frictionless. Ignore the vertical forces.](i) Find the acceleration of the blocks.(ii) Find the tension in the string

A block of mass m is attached, through an inextensible string and a massless spring of the spring constant k, to a bigger block by a rigid support as shown in the figure. The mass of the bigger block is M and all the contact surfaces are frictionless. The spring is initially at its natural length. If the system (block m) is released from rest, the maximum extension in the spring will b

Two masses m1 and m2 placed on a smooth horizontal surface are connected by a mass less, inextensible string. A horizontal force F is applied on m2 as shown in the figure, the tension in the string is 1 point

Two masses m1 and m2 are connected by a string over a frictionless pulley of negligible mass. The masses are released from rest. Air resistance is negligible.Mass m2 accelerates downwards at g2 . What is m1m2 ?
