Answer to Problem 1ASA
Centripetal force is the force acting on an object executing rotational motion and it is directed towards the center of the rotational path.
Explanation of Solution
The force which is responsible for keeping any object undergoing rotational motion, in the circular path is called the centripetal force. It is acting towards the center of the circular path and simply it can be stated that the centripetal force is responsible for the rotational motion.
Any object under rotation will have a centripetal force which is provided by the field in which it is moving. For a planet revolving around the sun, the centripetal force is provided by the gravitational force of attraction between the Sun and planet. For an electron revolving around the nucleus of an atom, the centripetal force is provided by the electrostatic force. The centripetal force always directed towards the center of the circular path.
