Question:medium

A large drop of oil (density 0.8 g/cm³ and viscosity \( \eta_0 \)) floats up through a column of another liquid (density 1.2 g/cm³ and viscosity \( \eta_L \)). Assuming that the two liquids do not mix, the velocity with which the oil drop rises will depend on:

Show Hint

The velocity of an oil drop rising in a liquid depends on the viscosity of the liquid, not the oil.

  • \( \eta_0 \) only
  • \( \eta_L \) only
  • both on \( \eta_0 \) and \( \eta_L \)
  • neither \( \eta_0 \) nor \( \eta_L \)
Show Solution

The Correct Option is B
