A particle released from rest is falling through a thick fluid under gravity. The fluid exerts a resistive force on the particle proportional to the square of its speed. Which one of the following graphs best depicts the variation of its speed v\mathrm{v} with time t−\mathrm{t}-A particle released from rest is falling through a thick fluid under gravity. The fluid exerts a resistive force on theA particle released from rest is falling through a thick fluid under gravity. The fluid exerts a resistive force on theA particle released from rest is falling through a thick fluid under gravity.
