As shown in figure, `A` is a man of mass `60 kg` standing on a block `B` of mass `40 kg` kept on ground. The coefficient of friction between the feet of the man and the block is `0.3` and that between `B` and the ground is `0.2` . If the person pulls the string with `125 N` force ,then

As shown in the figure, M is a man of mass 60kg standing on a block of mass 40kg kept on ground. The co - efficient of friction between the feet of the amn and the block is 0.3 and that between B and the ground is 0.1 . If the person pulls the string with 100N force, then :

As shown in the figure, M is a man of mass 60 kg standing on a block of mass 40 kg kept on ground. The co-efficient of friction between the feet of the man and the block is 0.3 and that between B and the ground is 0.1. If the man accelerates with an acceleration 2(m)/(s^2) in the forward direction, then,

As shown in the figure, M is a man of mass 60 kg standing on a block of mass 40 kg kept on ground. The co-efficient of friction between the feet of the man and the block is 0.3 and that between B and the ground is 0.1. If the man accelerates with an acceleration 2(m)/(s^2) in the forward direction, then,

A man pulls a block of mass equal to himself with a light string .The coefficient of friction between the man and the floor is greater than that between the block and the floor

A man pulls a block of mass equal to himself with a light string .The coefficient of friction between the man and the floor is greater than that between the block and the floor

A man pulls a block heavier than himself with a lioght rope. The coefficient if friction is the same between the man and the ground, and between the block and the ground.

A block A of mass 200 kg rest on a block B of mass 300 kg . A is tied with a horizontal string to a wall. Coefficient of friction between A and B is 0.25 and that between B and floor is 0.2 . The horizontal force F needed to move the block B is

The mass of block A is 100 kg and that of block B is 200 kg. The coefficient of friction between A and B is 0.2 and that between B and ground level is 0.3. The minimum force which will make the block B move, will be:
