Centripetal acceleration `a_(c) = (v^(2))/(R)` & Acceleration due to gravity `= g` So `g_(eff) = sqrt(g^(2) + ((v^(2))/(R))^(2)) rArr "Time period" T = 2pisqrt((L)/(g_(eff))) = 2pisqrt((L)/(sqrt(g^(2)+(v^(4))/(R^(2)))))`

A simple pendulum of length l and having a bob of mass M is suspended in a car. The car is moving on a circular track of radius R with a uniform speed v. If the pendulum makes small oscillations in a radial direction about its equilibrium position, what will be its time period ?
Consider a conical pendulum having bob is mass m is suspended from a ceiling through a string of length L. The bob moves in a horizontal circle of radius r. Find (a) the angular speed of the bob and (b) the tension in the string.
A simple pendulum of length L is constructed form a point object of mass m suspended by a massless tring attached to a fixed pivot point. A small peg is placed a distance 2L//3 directly below the fixed pivot point. A small peg is placed a distance 2L//3 directly below the fixed pivot point so that the pendulum would wing as shown in the figure. the mass is displaced 5 degrees form the vertical and released. How does it take to return to its starting position.
A simple pendulum has a length L and a bob of mass m. The bob is oscillating with amplitude A. Show that the maximum tension (T) in the string is (for small angular displacement). T_("max") =mg [1+(A/L)^(2)] .
A car is moving on circular path of radius 100m such that its speed is increasing at the rate of 5m//s^(2) . At t=0 it starts from rest. What is the radial acceleration of car at the instant it makes one complete round trip ?
A simple pendulum of length l and bob mass m is hanging in front of a large nonconducting sheet having surface charge density sigma . If suddenly a charge +q is given to the bob & it is released from the position shown in figure. Find the maximum angle through which the string is deflected from vertical . .
Consider a simple pendulum, having a bob attached to a string, that oscillates under the action of the force of gravity. Suppose that the period of oscillation of the simple pendulum depends on its length (l), mass of the bob (m) and acceleration due to gravity (g). Derive the expression for its time period using method of dimensions.
A simple pendulum of length 1m is allowed to oscillate with amplitude 2^(@) . it collides at T to the vertical its time period will be (use g = pi^(2) )
A simple pendulum of bob of mass m and length L has one of its ends fixed at the centre O of a vertical circle, as shown in the figure. If 0=60^(@) at the point P , the minimum speed u that should be given to the bob so that it completes vetical circle is
