Two blocks of masses 4kg and 2kg are connected by means of a string as shown in the figure. The coefficient of friction between the plane and the two blocks are 0.75 and 0.25 respectively. These blocks slip down an inclined plane with an angle of inclination 37 The common acceleration of the blocks in is:

A block of mass m is lying on a friction less plane inclined at an angle 30° It is connected to another block of mass m₂ with the help of a string over a pulley. If m₁=3Kg and m₂=4Kg then acceleration of each block is $\left(g={10}^m/s^2\right)$

When two masses m₁ and m₂ are hanging as shown in fig. and m₁> m₂ then the acceleration of bodies.

Two masses of 10kg and 20kg are connected by mass less spring as shown A force of 200N acts on the 20kg mass At a certain instant the acceleration of 10kg mass is $12m/s^2$ The acceleration of the 20kg mass at that instant is.

Two bodies of masses 5kg and 4kg are arranged on a table as shown in figure. The acceleration of 5kg block is.

Three equal masses A, B and C are pulled with a constant force F. They are connected to each other with strings. The ratio of the tension between AB and BC is.

The forces exerted by A on B, B on C, C on D and D on ground are.

Three masses of 16kg, 8kg, and 4kg are placed in contact as shown in figure. If a force of 140N is applied on 16kg mass the force acting on 8kg mass is.

Three blocks are connected as shown in the figure on a horizontal friction less table. If $M_1=1kg,M_2=8kg,M_3=27kg\text{ and }{T}_3=36N\text{ , }$then T₂ will be.

Two blocks of masses 2kg and 1kg are in contact with each other on a friction less table. When a horizontal force of 3N is applied on the block of mass 2kg, the value of the force of contact between the two blocks is.

Two masses m₁ and m₂ are placed on a smooth surface horizontally and connected by a light string as shown in figure A force F is applied on mass m₁, then the tension in the string T₂ is.

Two masses m₁ and m₂ are suspended from a rigid support through a light string. The tension in the string between support and mass m₁ is.

If the angle of friction is 45, then the coefficient of static friction is.

A block of mass 2kg lies on a horizontal surface and it is subjected to a vertical downward force 30N as shown in figure. The contact force between the block and surface is.
