If the steel ball is pulled upwards with a force equal to twice its effective weight; find the terminal velocity of the ball ( in cm/s ) in this case.

A small steel ball falls through a syrup at a constant speed of 10cm/sec. If the steel ball is pulled upwards with a force equal to twice its effective weight; find the terminal velocity of the ball ( in cm/s ) in this case.

each of radius 2 mm fall through aiir at a terminal velocity of 8 cm/s. If they coalesce to form a single drop n drops of water then the terminal velocity of the combined drop is 32 cm/s. Find n.
