A solid sphere falls with a terminal velocity of \( 20 \mathrm{~m} \mathrm{~s}^{-1} \) in
air. If it is allowed to fall in vacuum,
\( \mathrm{P} \)
(1) terminal velocity will be \( 20 \mathrm{~m} \mathrm{~s}^{-1} \)
W
(2) terminal velocity will be less than \( 20 \mathrm{~m} \mathrm{~s}^{-1} \)
(3) terminal velocity will be greater than \( 20 \mathrm{~m} \mathrm{~s}^{-1} \)
(4) no terminal velocity will be attained
