A body is placed on a smooth inclined plane of inclination 1 in x. The horizontal acceleration to be given to the inclined plane so that the body on it remains at rest with respect to inclined plane is
A particle is projected from the inclined plane at angle 37^(@) with the inclined plane in upward direction with speed 10m//s . The angle of inclined plane with horizontal is 53^(@) . Then the maximum height attained by the particle from the inclined plane will be-
A ball is projected from the bottom of an inclined plane of inclination 30^@ , with a velocity of 30 ms^(-1) , at an angle of 30^@ with the inclined plane. If g = 10 ms^(-2) , then the range of the ball on given inclined plane is
The upper half of an inclined plane with an angle of inclination theta, is smooth while the lower half is rough. A body starting from rest at the top of the inclined plane comes to rest at the bottom of the inclined plane. Then the coefficient of friction for the lower half is
A ring rolls down an inclined plane and acquires a velocity v upon reaching the bottom of the inclined plane. If another body rolls down from the same height over the same inclined plane and acquires a velocity sqrtfrac{6}{5}v upon reaching the bottom of the inclined plane, then that body is
A block of weight 1 N rests on a inclined plane of inclination theta with the horizontal. The coefficient of friction between the block and the inclined plane is mu . The minimum force that has to be applied parallel to the inclined plane to make the body just move up the plane is
A rough inclined plane is inclined at 30° to the horizontal as shown in the figure. A uniform chain of length L is partly on the inclined plane and partly hanging from the top of the incline. If the coefficient offriction between chain and inclined plane is mu , the maximum length of the lianging part to prevent the chain from falling vertically is:
A block of mass m is at rest on a rough inclined plane of angle of inclination theta . If coefficient of friction between the block and the inclined plane is mu , then the minimum value of force along the plane required to move the block on the plane is
A block is kept on a smooth inclined plane of angle of inclination theta that moves wuth a contact acceleration so that the block does not slide relative to the inclined plane. If the inclined plane stops the normal contact force offered by the plane on the block changes by a factor
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 :
