For finding the critical speed or the minimum speed in a question for a vertical plane, you take either the friction or the contact (normal) force to be 0, so F=W
However, for a horizontal plane, like spinning something around in a circle, you can still do F=W to find the critical speed or the minimum speed. Why is this?

When you say F do you mean centripetal force
