Whenever we throw ball in upward direction, it falls back to the ground under the Earth's gravity. In fact all objects near the Earth's surface fall with a constant acceleration of 9.8ms−2.
The correct option is A True Whenever we throw any object in upward direction, the gravitational pull acts on the body which is in downward direction. Hence it falls back to the ground under the action of Earth's gravity. Objects falling down under the influence of gravity, fall with a constant acceleration of 9.8 m/s².
