Question

If we go inside a mine and drop a $104lb$ iron ball and $1$ lb aluminum ball from the top of a high platform, neglecting air resistance.

• A. Both will reach the floor at the same time
• B. $1$ lb weight will reach the floor first
• C. $10$ lb weight will reach the floor first
• D. It is not possible to indicate which of the two will reach the floor first without further data

Answer 1

The correct option is A Both will reach the floor at the same time

In real life the one having less volume and more weight will reach first

but in ideal situation where viscosity of air is neglected both will hit ground at same time irrespective of their masses if dropped from the same height

this is because the acceleration produced due to gravity does not depend on the body.
