Chapter 2, Problem 1OQ
Two small heavy balls have the same diameter but one weighs twice as much as the other. The balls are dropped from a second-story balcony at the exact same time. The time to reach the ground below will be.
- twice as long for the lighter ball as for the heavier one.
- longer for the lighter ball, but not twice as long.
- twice as long for the heavier ball as for the lighter one.
- longer for the heavier ball, but not twice as long.
- nearly the same for both balls.
Expert Solution & Answer
To determine
The time taken for the two balls of different weight and same diameter to reach the ground.
Answer to Problem 1OQ
Solution:
Both the balls take nearly the same time to reach the ground.
Given:
Two balls of the same diameter but different weight.
Explanation of Solution
If the two balls with same diameter but different mass are thrown from a single storied building, then both balls will touch the ground at the exact time because the acceleration of the balls will not be affected by the weight of the balls. So, irrespective of the mass of the ball, the force applied on both balls will be the same.
Conclusion:
Both the balls will reach the ground at the same time irrespective of their weight and diameter.

A spaceship hovering over the surface of Saturn drops an object from a height of 12 m. How much longer does it take to reach the surface than if dropped from the same height on Earth? Neglect air resistance in both cases. [The acceleration due to gravity on Saturn is 91.6% of that on Earth, gSaturn = (0.916)g.]
