Two rings are suspended from the points A and B on the ceiling of a room with the help of string...

Two blocks are connected by a spring. The combination is suspended, at rest, from a string attatched to the ceiling, as shown in the figure. The string breaks suddenly. Immediately after the string breaks, what is the initial downward acceleration of the upeer block of mass 2m ?

A particle of mass 'm' and charge 'q' is suspended from the ceiling with the help of an insulating wire of length 'l' . It is placed in an uniform electric field as shown in figure. Then the time period of oscillation is

A block of mass 0.2 kg is suspended from the ceiling by a light string. A second block of mass 0.3 kg is suspended from the first block through another string. Find the tensions in the two strings. Take g=10 m/s^2 .

An ideal string is wrapped on a ring and the free end of the string is attached to the ceiling as shown in the figure. Initially, the system is held in equilibrium by an external agent and at some instant of time, the system is released from rest. If there is no slipping between the string and the ring, then the tension in the string is

A heavy rope is suspended from the ceiling of a room. If phi is the density of the rope, L be its original length and Y be its. Young's modulus, then increase DeltaL in the length of the rope due to its own weight is

A body of weight w_1 is suspended from the ceiling of a room through as chain of weight w_2 . The ceiling pulls the chain by a force

Two identical blocks are connected by a light spring. The combination is suspended at rest from a string attached to the ceiling, as shown in the figure-2.190 below. The string breaks suddenly. Immediately after the string breaks:

A wire is suspended from the ceiling and stretched under the action of weight F suspended from its other end. The force exerted by the ceiling on it is equal and opposite to the weight.
