Options

• 2Mg

• `"Mg"/2`

• Mg

• `3/2 "Mg"`

Answer 1

 

The velocity of a small ball of mass M and density d, when dropped in a container filled with glycerine becomes constant after some time. If the density of glycerine is `"d"/2`, then the viscous force acting on the ball will be `underline("Mg"/2)`.
