A small sphere of mass m is dropped from a great height. After it has fallen 100m, it attains the terminal velocity and continues to all at that speed. The work done by the air friction against the sphere during first 100m is

A small sphere of mass m is dropped from a aheight After it has fallen 100 m it has attained its terminal velocity and continues to fall at that speed. The work done by air friction against the sphere during the first 100 m of fall is-

A small sphere of mass m is dropped from a aheight After it has fallen 100 m it has attained its terminal velocity and continues to fall at that speed. The work done by air friction against the sphere during the first 100 m of fall is-

A small sphere of mass m is dropped from a aheight After it has fallen 100 m it has attained its terminal velocity and continues to fall at that speed. The work done by air friction against the sphere during the first 100 m of fall is-

A small sphere of mass 'm' is dropped from a great height. After it has fallen 100m, it has attained its terminal velocity and continue to fall at that speed. The workdone by air friction against the sphere during 100m fall is W_(1) and during next 100m fall is W_(2) , then compare W_(1) and W_(2) .

A small sphere of mass m is dropped from a height After it has fallen 100 m it has attained its terminal velocity and continues to fall at that speed. The work done by air friction against the sphere during the first 100 m of fall is-

A small sphere of mass m is drpped from a height. After it has fallen 100m, it has attained its terminal velocity and continues to fall at that speed. Then the modulus of work done.

Work done by 1kg of water when it falls through the height of 100m is

A body of mass 10 kg dropped from a height 20 m, acquires a velocity of 10m/s after a falling through a distance of 20m. What is the work done by the air resistance on the body?
