Problem
A mass–spring system is allowed to oscillate first in still air and then while completely submerged in thick oil at the same temperature. Which one of the following statements about the comparison of the two motions is correct?
(a) The amplitude falls more rapidly in oil, and the period becomes much longer.
(b) The amplitude falls more rapidly in oil, while the period changes only slightly.
(c) Both amplitude and period remain unchanged in the two media.
(d) The amplitude remains approximately the same, but the period becomes longer in oil.
