[Answer] A ball of mass m attached to a light string moves at a constant speed v in a vertical circle with a radius R. Which is true about the magnitude of the net force at point A compared to that at point B?

Answer: The net force at point A is equal to the net force at point B.

Fri Dec 21 2001 13:30:00 GMT-0500 (Eastern Standard Time) · The magnitude of the centripetal force on an object of mass m moving at tangential speed v along a path with radius of curvature r is: = = = → | | where is the centripetal acceleration and is the difference between the velocity vectors. Since the velocity vectors in the above diagram have constant magnitude and since each one is perpendicular to its respective position vector simple …

Tue Jan 15 2002 13:30:00 GMT-0500 (Eastern Standard Time) · Since the force is directed at right angles to the motion of the particle it moves with a constant speed around a circle whose radius is given by: R = v f {\displaystyle R ={\frac { v }{f}}\ } where f {\displaystyle f} is the Coriolis parameter 2 Ω sin ⁡ φ {\displaystyle 2\Omega \sin \varphi } introduced above (where φ {\displaystyle \varphi } is the latitude).
