A block of mass m is suspended by a light thread from an elevator. The elevator is accelerating upward with uniform acceleration a. The work done by tension on the block during t seconds is (u = 0)

A block of mass m is suspended by a light thread from an elevator. The elevator starting from rest is accelerating upward with uniform acceleratio a. The work done by tension on the block during t seconds is

A block of mass m is kept on a platform Platform starts moving upwards with an acceleration of g/2 . Find the work done by the normal force on the block in the first one second.

A block of mass m is kept on a platform Platform starts moving upwards with an acceleration of g/2 . Find the work done by the normal force on the block in the first one second.

A block of mass M is kept on a platform which is accelerated upward with a constant acceleration 'a' during the time interval T. The work done by normal reaction between the block and platform is

A block is kept on the floor of an elevator. The elevator starts descending with an acceleration of 12 m//s^(2) the displacement of the block during 1^(st) one second wth respect to elevator is-

A 6.0 kg object is suspended by a vertical string from the ceilling of an elevator which is acceleration upward at a rate of 2.2ms^(-2) . the tension in the string is

Two blocks of masses 2 kg and 4 kg are hanging with the help of massless string passing over an ideal pulley inside an elevator. The elevator is moving upward with an acceleration (g)/(2) . The tension in the string connected between the blocks will be (Take g=10m//s^(2) ).
