A simple pendulum having bob of maas m is suspended from the ceiling of a car used in a stunt film shooting. The car moves up along an inclined cliff at a speed v and makes a jump to leavwe the cliff and lands at some the top of the cliff. The tension in the string when the car is in air is

A

`mg`

B

`mg - (mv^(2))/(R )`

C

`mg + (mv^(2))/( R)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
Acceleration of car is "g" so `g_(eff) = vec g-vec a`.

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 wagon of mass M can move without friction along horizontal rails. A simple pendulum consisting of a sphere of mass m is suspended from the ceiling of the wagon by a string of length l. At the initial moment the wagon and the pendulum are at rest and the string is deflected through an angle alpha from the vertical. Find the velocity of the wagon when the pendulum passes through its mean position.
