Arock of mass m = 0.0450 kg is attached to one end of a string and is whirled around in a horizontal circle. if the radius of the circle is 0.580 m and the angular speed is 2.34 rad/s. what is the tension in the string?

Tension, T = 0.1429 N

Explanation:

Given that,

Mass of the rock, m = 0.0450 kg

Radius of the circle, r = 0.580 m

Angular speed,

The tension in the string is balanced by the centripetal force acting on it. It is given by :

Since,

T = 0.1429 N

So, the tension in the string is 0.1429 N. Hence, this is the required solution.

im sorry i dont know
