A small spherical ball of steel falls through a viscous medium with terminal velocity

v

. If a ball of twice the radius of the first one but of the same mass is dropped through the same method, it will fall with a terminal velocity (neglect buoyancy)

View answer and explanation

Correct option: A

\frac{v}{2}

Option A (v/2) is correct because the terminal velocity depends on the radius and density of the ball.

The tube is depressed more so that the top of capillary tube is only one cm above the liquid. Then the apparent angle of contact between the solid and liquid is An object weights
