Answer:
80 N
Step-by-step explanation:
the force of repulsion, F newtons (N), between two particles is inversely proportional to the square of the distance, D m, between the particles.
when the particles are a certain distance apart, the force of repulsion is 20 N. find the force when the distance is halved
F ∝ 1/D²
=> F = k/D²
Let say at distance = 2x the force of repulsion = 20N
=> 20 = k/(2x)²
=> k = 80x²
F = k/x²
=> F = 80x²/x²
=> F = 80 N
the force when the distance is halved = 80 N
