Answer:
Both balls hit the ground at the same time.
Step-by-step explanation:
Mass of lead ball=100 Kg
Mass of glass ball=1 kg
When Galileo dropped a lead ball and a glass ball from the learning tower of Pisa.
There is no air resistance.When Both ball from the learning tower of Pisa fall under the gravity effect.
The gravity effect for all bodies on the earth remains same .It does not vary with the mass.
Therefore, both ball hit the ground at the same time.
