Circular Motion PYQs - Last 5 Years

A motor cyclist starts from the top of an inclined plane of height $h$ to go around a globe of death trap of radius $r$. The ratio of minimum height ' $h$ ' of the inclined plane to the radius ' $r$ ' of the death globe in order to go aroun...

A point marked on a ring of radius 2 cm is in contact with a horizontal plane. Now the ring is rolled forward half a revolution along the positive X - direction. Then the angle made by the displacement vector of the point with the X - axis ...

A coin is placed on a disc rotating with an angular velocity $\omega$. The co-efficient of friction between the disc and the coin is $\mu$. The maximum distance of the coin from the centre of the disc up to which it will rotate with the dis...

A body is moving along a circular path of radius '\(r\)' with a frequency of revolution numerically equal to the radius of the circular path. What is the acceleration of the body if radius of the path is \(\left(\frac{5}{\pi}\right) m\) ?

A metal ball of \(20 \mathrm{~g}\) is projected at an angle \(30^{\circ}\) with the horizontal with an initial velocity \(10 \mathrm{~ms}^{-1}\). If the mass and angle of projection are doubled keeping the initial velocity the same, the rat...

A ball is moving in a circular path of radius \(5 \mathrm{~m}\). If tangential acceleration at any instant is \(10 \mathrm{~ms}^{-2}\) and the net acceleration makes an angle of \(30^{\circ}\) with the centripetal acceleration, then, the in...

One end of the string of length $l$ is connected to a particle of mass \(m\) and the other end is connected to a small peg on a smooth horizontal table. If the particle moves in circle with speed \(v\), the net force on the particle (direct...
