Fruits detached from a tree fall down due to force of gravity. We know that a force arises due to interaction between two objects. Name the objects interacting in this.

When fruits detached from a tree fall down due to force of gravity, the objects interacting in this are fruits and earth.

i. As soon as the fruits detached from a tree, earth applies its force of gravity on fruit.

ii. The force of gravity will act towards the centre of the fruit.

iii. Hence, the pull of the earth causes fruits to falls down and interact with the earth.
