A stone tied to a string is rotated in a vertical circle. The minimum speed of the stone during a complete vertical circular motion

Question

A stone tied to a string is rotated in a vertical circle. The minimum speed of the stone during a complete vertical circular motion (A) is independent of the mass of the stone. (B) is independent of the length of the string. (C) decreases with increasing mass of the stone. (D) decreases with increasing length of the string.

Minimum speed with which the string is rotating in a vertical circle, (.v.)=√g r i.e, the minimum speed of stone is independent of the mass of stone.

is independent of the mass of the stone.

is independent of the length of the string.

decreases with increasing mass of the stone.

decreases with increasing length of the string.

Minimum speed with which the string is rotating in a vertical circle, $(v) = g r$
i.e, the minimum speed of stone is independent of the mass of stone.
