Question

You observe an object moving clockwise in a circle, with increasing angular speed. What can you conclude about the net force acting on that object?

a. The force has a radial component which is positive, i.e. it points away from the center of the circle, like a centrifugal force

b. The given information does not allow us to determine whether the net force has a radial component and, if it is there, what its sign is.

c. The force has a non-vanishing radial component which is negative, i.e. it points to the center of the circle.

d. The radius of the motion is constant, so the radial component of the net force is zero

Apply linear speed v= r*w

the body moves in a circle due to centripetal or radial component of force

So the answer is c. The force has a non-vanishing radial component which is negative, i.e. it points to the center of the circle.
