Explanation:
Force of attraction between two objects i.e. F=GMm/r².
If the distance is reduced to half, new distance = r/2
So, new force of attraction= GMm/(r/2)²
=GMm/(r²/4)
=4GMm/r²
Hence, the new force of attraction becomes 4 times the original force of attraction when distance is reduced to half.
