The number of paperclips the magnet will pick when held at 15 cm away is 2 paperclips
Thus, as the distance increase, the amount of paper clips the magnet will pick will reduce. This is illustrated below
p ∝ 1 / d
p = K / d
Cross multiply
pd = constant
p₁d₁ = p₂d₂
p₁d₁ = p₂d₂
3 × 10 = p₂ × 15
30 = p₂ × 15
Divide both side by 15
p₂ = 30 / 15
p₂ = 2
