The work done by the normal reaction on the rod is :

A block of mass m is placed on a smooth wedge of inclination theta & mass M. The whole system is slip on the wedge. Then the normal reaction on the wedge acting from the ground :

A block of mass 10 kg is released on a fixed wedge inside a cart which is moving with constant velocity 10 ms^(-1) towards right. There is no relative motion between block and cart. Then work done by normal reaction on block in two seconds from ground frame will be ( g=10 ms^(-2) )

A block of mass 10kg is released on a fixed wedge inside a cart which is moved with constant velocity 10m//s towards right. Take initial velocity of block with respect to cart zero. Then work done by normal reaction (with respect to ground) on block in two second will be :(g=10 m//s^(2)) .

A small block of mass 1 kg is kept on a rough inclined wedge of inclination 45^@ fixed in an elevator. The elevator goes up with a uniform velocity v=2 m//s and the block done not slide on the wedge. Find the work done by the of friction on the block in 1s . (g=10 m//s^(2))

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 of mass m is kept on a platform which starts from rest with constant acceleration g/4 upward, as shown in the figure. Work done by normal reaction on block in time t is:

A block of mass m is kept on a platform which starts from rest with constant acceleration g/2 upward, as shown in fig. Work done by normal reaction on block in time t is :
