In the abjoining figure, wire `PQ` is smooth, ring `A` has a mass `1kg` and block `B,2kg`

In the arrangement shown in figure , find the retio of tension in the strings attached with 4kg block and the with 1kg block

The elevator shown in figure is descending with an acceleration of 2m/s^2 . The mass of the block A is 0.5 kg. What force is exerted by the block A on the block B?

in the figure shown all surface are smooth. Find (a)acceleration of all the blocks, (b) net force on 4kg and 10kg blocks and , ( c) force acting between 4kg and 10kg blocks.

Two unequal masses of 1kg and 2kg are connected by an inextensible light string passing over a smooth pulley as shown in figure. A force F = 20N is applied on 1kg block find the acceleration of either block (g = 10m//s^(2)) .

Three blocks of masses 3kg ,2kg and 1kg are placed side by side on a smooth surface as shown in figure. A horizontal force of 12N is applied on 3kg block. Find the net force on 2kg block.

Two block of mass 1 kg and 2 kg are connected by a string AB of mass 1 kg . The blocks are placed on a smooth horizental surfacec. Block of mass 1 kg is pulled by a horizental force F of magnitude 8 N . Find the tension in the string at points A and B

Find out the acceleration of 2kg block in the figures shown at the instant 1kg block falls from 2kg block ( at t = 0 )
