Live ChatA small steel ball of radius r is allowed to fall under gravity through a column of viscous liquid of coefficient η. After some time the velocity of the ball attains a constant value known as terminal velocity V T.The terminal velocity depends on mass of the ball m coefficient of viscosity η the radius of the ball r and acceleration due to gravity g.
Live Chat1. Weigh the balls measure their radius r and hence calculate the density ρ of the balls. 2. Place three rubber bands around the tube. The highest should be far enough below the surface of the liquid to ensure the ball is travelling at terminal velocity when it reaches this band. This is where the timer is started.
