A body slides without friction from a height `H = 60 cm` and then loops the loop of radius `R = 20 cm` at the bottom of an incline. Find the ratio of forces exerted on the body by the track at the positions `A,B` and `C (g = 10 ms^(-2))`.

A body slides without friction from a height H = 60 cm and then loops the loop of radius R = 20 cm at the bottom of incline. The ratio of forces exerted on the body by the track at A,B and C are (g = 10 ms^(-2))

A small object slides without friction from the height 5R//2 and then loops of the verticle loop of radius R from which a symmetrical section of angle 2alpha has been removed. Find angle alpha such that after losing contact at A and flying through the air, the object will reach point B .

A body slides down a fixed curved track that is one quadrant of a circle of radius R , as in the figure. If there is no friction and the body starts from rest, its speed at the bottom of the track is

A body slides down an inclined surface which ends into a vertical loop of radius R = 40cm. What must be the height H of the inclined surface for the body so that it does not leave contact with the surface even at the uppermost point of the loop? Assume friction to be absent.

Water is filled in a flask upto a height of 20cm . The bottom of the flask is circular with radius 10 cm . If the atmospheric pressure is 1.013xx10^(5) Pa, find the force exerted by the water on the bottom . Take g=10 "ms"^(-2) and density of water =1000 "kgm"^(-3).

The block on the loop shown slides without friction. At what height from A it starts so that it passes against the track at B with a net upward force equal to its own weight? The radius of the loop is R.
