A sphere kept on a rough inclined plane is in equilibrium by a string wrapped over it. If angle of inclination is `theta`, the tension in string will be equal to

A uniform thin hemispherical shell is kept at rest and in equilibrium on an inclined plane of angle of inclination theta=30^(@) as shown in figure. If the surface of the inclined plane is sufficiently rough to prevent sliding then the angle alpha made by the plane of hemisphere with inclined plane is :

A non uniform sphere can be kept on a rough inclined plane so that it is in equilibrium. In the figure below the dots representsm location of centre of mass. In which one of the positions can sphere be in equilibrium ?

A block of mass m is kept on an inclined plane is angle inclination theta ( lt phi), where phi= angle of friction. Then :

For the system shown in the figure, the inclined plane is fixed, all the pulleys are light and friction is absent every where.The tension in the string will be

A hollow sphere rolls down a rough inclined plane whose angle of inclination is theta , with horizontal. For the hollow sphere to undergo pure rolling, without slipping, the condition is [ mu = coefficient of friction between the hollow sphere and inclined plane]
