A solid ball of volume V is dropped in a viscous liquid. It experiences a viscous force F . If the solid ball of volume 2 V of same material is dropped in the same fluid, then the viscous force acting on it will be

Options

  1. An F / 2
  2. BF / 2
  3. C2 F
  4. D2 n F

Correct answer

C. 2 F

Step-by-step solution

Viscous force, F=6 r v but v r² array lll F V & (volume) array So, on doubling the volume of the ball, the viscous force is doubled.
