A boy hold an apple. Why doesn't gravity cause the apple to fall to the
ground?

The force of his hand pushes up on the apple with
equal magnitude to the force of gravity, which pulls
down on the apple. The two forces are balanced,
so the apple doesn't fall.
The force of his hand pushes up on the apple with
greater magnitude than the force of gravity, which
pulls down on the apple. The two forces are
unbalanced, so the apple doesn't fall.

The correct answer is: The force of his hand pushes up on the apple with equal magnitude to the force of gravity, which pulls down on the apple. The two forces are balanced, so the apple doesn't fall.
Explanation:
Gravity is the force that attracts objects towards each other. In this case, the force of gravity is pulling the apple downward towards the ground. However, the boy is holding the apple in his hand, and his hand is exerting an upward force on the apple.
For the apple to stay in place and not fall, the upward force exerted by the boy's hand must be equal in magnitude to the downward force of gravity. When these two forces are balanced, the net force on the apple is zero. As a result, the apple remains in the boy's hand without falling to the ground.
It's important to note that if the downward force of gravity were to become greater than the upward force exerted by the boy's hand, the net force would no longer be zero, and the apple would fall towards the ground.
