Achild twirls his yo-yo horizontally about his head rather than using it properly. the yo-yo has a mass of 0.200 kg and is attached to a string 0.800 m long. (a) if the yo-yo makes a complete revolution each second, what tension must exist in the string?

Tension in the string, F = 6.316 N

Explanation:

It is given that,

Mass of the Yo - Yo, m = 0.2 kg

Length of the string, l = 0.8 m

It makes a complete revolution each second, angular velocity,

Let T is the tension exist in the string. The tension acting on it is equal to the centripetal force acting on it. Its expression is given by :

F = 6.316 N

So, the tension must exist in the string is 6.316 N. Hence, this is the required solution.

reserve is the answer

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
