If a body connected with a string length r is applied a velocity of √(3rg) at what angle its velocity will become zero
The body is moving in a circular path of radius r and is connected to a string. The velocity of the body is given as (3rg) and we need to find the angle at which its velocity becomes zero.
The velocity of a body moving in a circular path of radius r is given by v = ωr, where ω is the angular velocity of the body.
The centripetal force required to keep the body moving in a circular path is given by F = mv^2/r = mω^2r.
In this problem, the body is initially moving with a velocity of (3rg) and is...
