Two equal masses of mass M each are attached to a string passing over a smooth pulley which is attached by a chain to the celiling. The tension in the chain is:

A

0

B

Mg

C

2Mg

D

`(1)/(2)Mg`

Text Solution

Verified by Experts

The correct Answer is:
c

Here,`T=(2Mm)/(M+m)g`Now M=m
`T=(2MxxM)/(2M)g=Mg`
Tension in the chain `= 2T = 2Mg`
(c) is the choice.

Two masses M_1 and M_2 are attached to the ends of a string which passes over a pulley attached to the top of an inclined plane Theta . The gangle of inclination of the plane is 0. Take g = 10 ms^-2 . If M_1 = 10 kg . M_2 = 5 kg , Theta = 30 , the acceleration of mass M_2 is

An ideal spring with spring-constants bung from the celling and a block of mass M is attached to its lower end. The mass is released with the spring initially unstretched. Then the maximum extension in the spring is:

Two masses 8 kg and 12 kg are connected at the two ends of a light inextensible string that goes over a frictionless pulley. Find the acceleration of the masses, and the tension in the string when the masses are released.

Two bodies of masses 6 kg and 4 kg respectively are connected to two ends of a light string passing over horizontal frictionless pulley. The acceleration in the string is :

Two weights w, and w, are attached to the ends of a string which passes over a frictionless pulley. If the pulley is placed in a lift rising up with an acceleration equal to that of gravity i.e. '8', the tension in the string :

Two particles of mass m each are tied at the ends of a light string of length 2a. The whole system is kept on a frictionless horizontal surface with the string held tight so that each mass is at a distance 'a' from the center P (as shown in figure). Now, the mid-point of the string is pulled vertically upwards with a small but constant force F. As a result, the particles move towards each other on the surface. The magnitude of acceleration, when the separation between them becomes 2x, is :
