Question

a simple pendulum of mass m making a constant angle tetha with the verticle .the angular velocity of the trooly centre of curvature of the circular track of radious R. Find the value of W​

Answer 1

Explanation:

Tension not only provides the centripetal force necessary for circular motion but also balances the component of weight along the string.

component of weight along the string is mgcosθ.

Thus, T−mgcosθ=

L

mv

⇒T=mgcosθ+
