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.

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
