A ball of mass 100 g released down an inclined plane describes a circle of radius 10 cm in the vertical plane on reaching the bottom of the inclined plane. The minimum height of the incline is

A solid cylinder and a solid sphere roll down on the same inclined plane. Then ratio of their acclerations is

A body' of mass m slides down on an inclined plane and reaches'the bottom with a velocity V. If the same mass were in the form of a ring which rolls down on the inclined plane, then the velocity of the ring at the bottom will be

A solid cylinder at rest at top of an inclined plane of height 2.7 m rolls down without slipping. If the same cylinder has to slide down a frictionless inclined plane and acquires the same velocity as that acquired by centre of mass of rolling cylinder at the bottom of the incline, what should be the height of the inclined plane?

A weightless thread can support tension up to 30N.A particle of mass 0.5kg is tied to it and is revolved in a circle of radius 2m in a verticle plane. If g=10m//s^(2) , then the maximum angular velocity of the stone will be

A solid cylinder of mass 0.1 kg having radius 0.2 m rolls down an inclined plane of height 0.6 m without slipping. The linear velocity of the cylinder at the bottom of the inclined plane is

A body of mass 10kg is placed on a smooth inclined plane making an angle of 30^(@) with the horizontal, the component of the force of gravity trying to move the body down the inclined plane is [g=9.8m//s^(2)]

A stone of mass 1kg tied to a light inextensible string of length L=10m is whirling in a circular path of radius L in vertical plane. If the ratio of the maximum tension in the string to the minimum tension in the string is 4 and if g is taken to be 10ms^(-2) , the speed of the stone at the highest point of the circle is.

A body of mass 2 kg is attached to a cord and whirled in a vertical circle of radius 2 m. The minimum speed at the bottom of the circle so that the cord will not slacken when the body rounds the top of the circle will be

A solid cylinder rolls down on inclined plane. Its mass is 2kg and radius 0.1m. If the height of the inclined plane is 4m, what is its rotational K.E. when it reaches foot of the plane? Take M.I. of solid cylinder about its axis = frac( Mr^2)(2) .

A block of mas M is resting on an inclined plane as shown in the figure. The inclination of the plane to the horizontal is gradually increased. It is found that when the angle of inclination is theta the block just begins to slide down the plane. What is the minimum force F applied parallel to the plane that would just make the block move up the plane ?
