Answer:
Centripetal force, F = 9.81 N
Step-by-step explanation:
It is given that,
Mass of the object (yo-yo), m = 0.12 kg
It is whirled around by its string in a circle
Radius of circle, r = 0.44 m
Speed of object, v = 6 m/s
We need to find the required centripetal force in Newtons to keep this yo -yo whirling in a circle. The centripetal force is given by :


F = 9.81 Newton
So, the centripetal force required to keep this yo -yo whirling in a circle is 9.81 N. Hence, this is the required solution.
