Two smooth prisms of similar right-triangular sections are arranged on a smooth horizontal plane as shown in figure. The lower prism has a mass `eta` times the upper prism. The prisms are held in an initial position as shown and are then released. As the upper prism touches the horizontal plane, the distance moved b y the lower prism is

A

B

`(a-b)/(eta)`

C

`(a-b)/((1-eta))`

D

A triangular block ABC of mass m and side 2a lies on a smooth horizontal plane is shown. There point masses of the m each strikes the block at A, B and C with speed as shown. After the collision the particle come to rest. Then

A triangular prism of mass m placed on it is released from rest on a smooth inclined plane of inclination theta The block does not slip on the prism. Then

Two blocks each of the mass m are attached to the ends of a massless rod which pivots as shown in figure. Initially the rod is held in the horizontal position and then released. Calculate the initial angular acceleration.

A body with a mass m slides along the surfac of a trihedral prism of mass M, whose upper plane is inclined at an angle alpha to the horizontal. The prism rests on a horizontal plane having a vertical ledge at the rear edge of the prism to keep it at rest as show in figure-2.69. Find the force exerted by the base of the prism on the plane ? Also find the force exerted by ledge on prism. [Mg +mgcos^(2)alpha, mg sinalphacosalpha]

Consider an equilateral prism as shown in the figure. The mass of the prism is M and length of each side of its cross section is a . Find the moment of inertia of such a prism about the central axis shown.
