Lead ball falls through water more slowly than through air because __________?
Correct answer: C. Of the viscous force in water
- A. The value of 'g' is less in water
- B. Density of air is less than that of water
- C. Of the viscous force in water
- D. Of The surface tension of water
Explanation
Water exerts greater viscous resistance on the falling ball than air does, opposing its motion more strongly. The value of gravitational acceleration is essentially the same in air and water.
