Question

two balls p and q having masses 2 kg and 4 kg respectively are dropped from the same height simultaneously. show that they will reach the ground simultaneously.

Answer 1

2kg and 4 kg are considerable weights which can not be much affected by air resistance if the height is small. They both will fall with acceleration equal to that of gravitational. 9.81 mps2. Hence without any issue both with reach simultaneously.

The same fact can not be effective if masses are compared with feathers.
