A block of mass 10kg is being brought down slowly by a light string through is distance of 2m.Mark the correct option.

A block of mass 10 kg is suspended through two light spring balance as shown below:

A block of mass 30.0 kg is being brought down by a chain. If the block acquires as speed of 40.0 (cm)/s in dropping down 2.00 m ,find the work done by the chain during the process.

A block of mass 2 kg is being brought down by a string. If the block acquires a speed 1(m)//(s) in dropping down 25 cm, find the work done by the string in the process.

A block of mass 10 kg is hanging over a smooth and light pulley through a light string and the other end of the string is pulled down by a constant force F. The kinetic energy of the block increases by 20 J in 1 s

A block of mass 2 kg is hanging from a light, smooth pulley through a light string. The kinetic energy of block increased to 16 J in 2 s by applying a constant force F on one end of upper string. Then

A block of mass 2 kg is hanging over a smooth and light pulley through a light string. The other end of the string is pulled by a constant force F = 40 N. The kinetic energy of the particle increases 40 J in a given interval of time. Then, (g = 10 m//s^(2))

A block of mass 2 kg is hanging over a smooth and light pulley through a light string. The order end of the string is pulled by a constant force F = 40 N . The kinetic energy of the particle increase 40 J in a given interval of time. Then : (g = 10 m//s^(2)) . .

A block of mass 20 kg tied to a string is being brough down strating from state of rest . Block axquires a speed of 1 m/s after descending a height of 5 m . Calculate work done by tension of string during the process .

A block of mass 20 kg is moving on a smooth surface by pulling through a light string of tension 10sqrt2 N. Find the work done by string on the block for a displacement of 2 m along the surface.
