A simple pendulum is released from rest at the horizontally stretched position. When the string makes an angle theta with the vertical, the angle theta which the acceleration vector of the bob makes with the string is given by–

A nail is located at a certain distance vertically below the point of suspension of a simple pendulum. The pendulum bob is released from a position where the string makes an angle of 60^(@) with the vertical. Calculate the distance of nail from the point of suspension such that the bob will just perform revolutions with the nail as centre. Assume the length of the pendulum to be one meter.

A nail is fixed at a point P vertically below the point of suspension 'O' of simple pendulum of length 1 m . The bob is released when the string of pendulum makes an angle 30^@ with horiozontal. The bob reaches lowest point and then describes vertical circle whose centre coincides with P . The least distance of P from O is

A heavy small sized sphere is suspended by a string of length l . The sphere rotates uniformly in a horizontal circle with the string making an angle theta with the vertical. Then the time period of this conical pendulum is-

A simple pendulum of length L has a bob of mass m. The bob is connected to light horizontal spring of force constant k. The spring is relaxed when the pendulum is vertical (see fig (i)). (a) The bob is pulled slightly and released. Find the time period of small oscillations. Assume that the spring remains horizontal. (b) The spring is replaced with an elastic cord of force constant k. The cord is relaxed when the pendulum is vertical (see fig (ii)). The bob is pulled slightly and released. Find the time period of oscillations.
