A car moves in a circular motion and it is subject to a centripetal acceleration of 24 m/s2. If the radius of the circular path is double, what is the centripetal acceleration?

Explanation:

Centripetal acceleration is given by:

Thus, centripetal acceleration is inversely proportional to the radius. Thus, when radius will double, the centripetal acceleration will be halved.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
