1 Answer

Answer :

(1) Both the spheres will reach the ground simultaneously. Explanation: If no air resistance is present, the rate of descent depends only on how far the object has fallen, no matter how heavy the object is. This means that two objects will reach the ground at the same time if they are dropped simultaneously from the same height.
