Two stones of unequal masses are thrown vertically up with the same velocity. Which of the following will happen?
A. The heavier mass will reach greater height
B. The lighter mass will reach greater height
C. Both will reach the same height
D. Any of them may reach greater height
Answer: Option C
Solution(By Examveda Team)
Galileo’s experiment showed that if two bodies of unequal masses are dropped from the same height, the time required by them to reach the ground are equal. If they are thrown vertically upwards with the same initial velocity, then the ratio of the time required to reach the ground is equal to unity. This means that both of them will reach the same height.This Question Belongs to General Knowledge >> Physics
