A bob of mass m is suspended by a light string of length L. It is imparted a horizontal velocity `v_0` at the lowest point a such that it completes a semi-circular trajectory in the vertical plane with the string becoming slack only on reaching the topmost poin, C. This is shown in Figure. Obtain an expression for `v_0`

A bob of mass m is suspended by a light string of length L. It is imparted a horizontal velocity v_(0) at the lowest point A such that it completes a semi-circular trajectory in the vertical plane with the string becoming slack on reaching the topmost point C, figure, Obtain an expression for (i) v_(0) (ii) the speeds at points B and C, (ii) the ration of kinetic energies (K_(B)//K_(C)) at B and C. Comment on the nature of the trajectory of the bob after it reahes the poing C.

A bob of mass ‘m’ is suspended by a light string of length ‘L’. It is imparted a minimum horizontal velocity at the lowest point A such that it just completes half circle reaching the top most position B. The ratio of kinetic energies frac{(K.E.)_A}{(K.E)_B} is

A body of mass m is suspended from a string of length l . What is minimum horizontal velocity that should be given to the body in its lowest position so that it may complete one full revolution in the vertical plane with the point of suspension as the centre of the circle

A bob of mass m suspended by a light string of length L is whirled into a vertical circle as shown in figure . What will be the trajectory of the particle if the string is cut at (a) Point B ? (b) Point C? (c) Point X?

A body is suspended by a string of length l is projected with horizontal velocity V such that it does not complete the motion in vertical circles.Then the height at which tension becomes is zero is given by?

A bob of mas M is suspended by a massless string of length L . The horizontal velocity v at position A is just sufficient to make it reach the point B . The angle theta at which the speed of the bob is half of that at A , satisfies. .

A paricle of mass m is tied to a light string of length L and moving in a horizontal circle of radius r with speed v as shown. The forces acting on the particle are

A mass m is hanging by a string of length l. The velocity v_(0) which must be imparted to it to just reach the top is
