Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

6) In the figure shown, body A is connected to
body B by a cord which goes through smooth

As shown in the figure, a ball of mass m is connected to a string of length I to the top of a cone with frictionless sides. The cone is resting on the horizontal surface and the axis of the cone is vertical, making an angle of 30° with the side surface of the cone. The ball moves in a horizontal circle at a uniform speed v centered about the vertical axis of the cone. If the velocity v of the ball is greater than a certain velocity vo, it will lose contact with the surface of the cone and the angle o between the string and the vertical will no longer be 30°. 30! i.
