A stone tied to a string is rotated in a vertical circle. The minimum speed with which the stone has to be rotated in order to complete the circle :

Question

Verified by Toppr

Answer 1

We can use the conservation of energy equation to find minimum speed required for completing the circle
$V = 5 R g$ (this speed is minimum speed required for completing the circle)
i.e. independent of the mass of the stone.

Answer 2

We can use the conservation of energy equation to find minimum speed required for completing the circle

V = 5 R g

(this speed is minimum speed required for completing the circle)
i.e. independent of the mass of the stone.

A stone tied to a string is rotated in a vertical circle. The minimum speed with which the stone has to be rotated in order to complete the circle :

decreases with increasing the mass of the stone

is independent of the mass of the stone

decreases with increasing the length of the string

is independent of the length of the string

Solution

is independent of the mass of the stone

We can use the conservation of energy equation to find minimum speed required for completing the circle
$V = 5 R g$ (this speed is minimum speed required for completing the circle)
i.e. independent of the mass of the stone.
