361381 What is the velocity \(v\) of a metallic ball of radius \(r\) falling in a tank of liquid at the instant when its acceleration is one-half that of a freely falling body?(The densities of metal and of liquid are \(\rho\) and \(\sigma\), respectively and the viscosity of liquid is \(\eta\) )

361382 What is the velocity \(v\) of a metallic ball of radius \(r\) falling in a tank of liquid at the instant when its acceleration is one-half that of a freely falling body? (The densities of metal and of liquid are \(\rho\) and \(\sigma\) respectively, and the viscosity of the liquid is \(\eta\) )

361383 Two rain drops reach the earth with different terminal velocities having ratio \(9: 4\). Then the ratio of their volume is

361384 Assertion :
Terminal velocity is same as the critical velocity
Reason :
The constant velocity of fall of a body through a viscous fluid is called terminal velocity.
