A small sphere of mass 'm' is attached to a cord and rotates in a vertical plane about a point `O`. If the average speed of the sphere is increased, the cord is most likely to break at the orientation when the mass is at :
.

A mass is performing vertical ciruclar motion . If the average velocity of the particle is increased, then at which point the string will break:

A small sphere B of mass m is released form rest in the position shown and swings freely in a vertical plane, first about O and then about the peg A after the cord comes in contact with the peg. Determime the tension in the cord (a) just before the sphere comes in contact with the peg. (b) just after it comes in contact with the peg.

A mass m is attached to a thin wire and whirled in a vertical circle. The wire is most likely to break when:

A heavy mass is attached to a thin wire and is whirled in a vertical circle. The wire is most likely to break

Find the moment of inertia of a sphere about a tangent to the sphere, while the mass of the sphere is M and the radius of the sphere is R.

A small ball of mass m is attached to a string of lengh R and moves in a vertical circle with a speed v m/s about a fixed point O as illustrated in fig. Find the tension in the string, when it makes an angle theta with the vertical, in terms of v, theta and g.

A small sphere of mass m suspended by a thread is first taken a side so that the thread forms the right angle with the vertical and then released, then

A body of mass 2 kg attached to a cord and whirled in a verticle circle of radius 2 m. The minimum speed at the bottom of the circle so that the cord will not slacken when the body rounds the top of the circle will be (g=10 m//s^(2))
