A body shown in figure is accelerating downward with acceleration 2 m/s². The tension in the string is

One end of massless rope, which passes over a massless and frictionless pulley P is tied to a hook C while the other end is free. Maximum tension that the rope can bear is 360 N, with what value of minimum safe acceleration ( in ms^–2) can a monkey of 60 kg move down on the rope?

A light string passing over a smooth light pulley connects two blocks of masses m₁ and m₂ (vertically). If the acceleration of the system is g/8, then the ratio ofthe masses is

Two masses m₁ = 5 kg and m₂ = 4.8 kg tied to a string are hanging over a light frictionless pulley. What is the acceleration of the masses when they are free to move?(g = 9.8 m/s²)

A block of mass 4 kg is suspended through two light spring balances A and B. Then, A and B will read respectively

Two blocks are connected by a string as shown in the diagram. The upper block is hung by another string. A force F applied on the upper string produces an acceleration of 2 m/s² in the upward direction in both the blocks. If T and T\' be the tensions in the two parts of the string, then (g = 9.8 m/s²)

Consider the following statements about the blocks shown in the diagram that are being pushed by a constant force on a frictionless table
A. All blocks move with the same acceleration
B. The net force on each block is the same Which of these statements are/is correct?

Two blocks A and B masses 2m and m, respectively, are connected by a massless and inextensible string. The whole system is suspended by a massless spring as shown in the figure. The magnitudes of acceleration of A and B, immediately after the string is cut, are respectively

In the arrangement shown, the pulleys are fixed and ideal, the strings are light, m₁> m₂ and S is a spring balance which is itself massless. The reading of S(in unit of mass) is
