Chapter 9 – Circular Motion

A particle A of mass m is attached to a vertical axis by two stings PA and QA of lengths 3L and 4L , respectively. PQ=5L. A rotates around the axis with an angular speed ω. The tension in the two strings are T1 and T2. A particle A of mass m is attached to [...]

A string of length L is fixed at one end and carries a mass M at the other end. The string makes 2/π revolution per second around the vertical axis through the fixed end as shown in the figure, then tension in the string is. A string of length L is fixed at one end [...]

A bucket tied at the end of a 1.6m long string is whirled in a vertical circle with constant speed. What should be the minimum speed so that the water from the bucket does not spill, when the bucket is at the highest position (Take g=10m/s^2) A bucket tied at the end of a 1.6m [...]

Consider a car moving on a horizontal road, convex bridge and concave bridge of same radius R. The speed of the car in each situation is same and equal to v, the mass of the car is m, then Consider a car moving on a horizontal road convex bridge and concave bridge of same radius [...]

A motorcycle is going on an over bridge of radius R. The driver maintains a constant speed. As the motorcycle is ascending on the over bridge, the normal force on it A motorcycle is going on an over bridge of radius R. The driver maintains a constant speed. As the motorcycle is ascending on the [...]

A bridge is in the form of a semicircle of radius 40m. The greatest speed with which a motorcycle can cross the bridge without leaving the ground at the highest point (frictional force is negligibly small) A block is released on a smooth track from A. The minimum value of h so that the block [...]

A small disc is on the top of a hemisphere of radius R. What is the smallest horizontal velocity v that should be given to the disc for it to leave the hemisphere and not slide down it?[There is no friction] A block is released on a smooth track from A. The minimum value of [...]

A Particle is kept at rest at the top of a sphere of diameter 42 m. when disturbed slightly, it slides down. At what height h from the bottom, the particle will leave the sphere. A Particle is kept at rest at the top of a sphere of diameter 42 m. when disturbed slightly it [...]

A particle is released from the top of the smooth hemisphere R as shown. the normal contact between the particle and the hemisphere in position θ is A particle is released from the top of the smooth hemisphere R as shown. the normal contact between the particle and the hemisphere in position θ is October [...]
