The force acting on the object is

#### Explanation:

We'll start by determining the velocity of the object. Since it is revolving in a circle of radius 8m 6 times per second, we know that:

Plugging in values gives us:

Now we can use the standard equation for centripetal acceleration:

And to finish the problem we simply use the given mass to determine the force needed to produce this acceleration:
