Homework Statement
A body can move in a circle at a constant speed if
a. there is an unbalanced radial force directed inwards.
b. inward and outward forces are equal in magnitude
c. the net radial forces equal the net tangential forces
d. all the statements above are correct
e. none of the statements above are correct
Homework Equations
I think centripetal force is related to this question, but I'm not sure if it is needed to explain it.
Fc = (mv2)/r
The Attempt at a Solution
I tried reading this in my book and looking it up online, but with my thinking, everything seems to be contradicting each other and I am not sure how to process it. All I have gotten from them seems to be that there is a centripetal force towards the axis of rotation that produces a centripetal acceleration with changing velocity, but constant speed. I think there is a radial force inwards, but I'm not sure whether or not to say if it is unbalanced or not?
