Answer:
Since steel contains iron (a magnetic metal), the magnets will attract the steel cans since aluminum is not magnetic. This is used to separate the steel cans from the aluminum cans so they can be recycled separately.
The charge on each of the equally charged drops of hairspray willl be 7 × 10 ⁻¹³ C
<h3>What is Columb's law?</h3>
The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Similar charges repel each other, whereas charges that are opposed attract each other.
Given data;
Electric force,F = 9 × 10 ⁻⁹ N
Distance between charges,d = 7 × 10⁻⁴ m
Chrge,q₁ = q₂ =q C
From Columb's law;
![\rm F = K \frac{q_1q_2}{d^2} \\\\ 9 \times 10^{-9} = 9 \times 10^9 \frac{q^2}{(7 \times 10^{-4})^2} \\\\ q^2 = 4.9 \times 10^{-25} \\\\ q = 7 \times 10^{-13} \ C](https://tex.z-dn.net/?f=%5Crm%20F%20%3D%20K%20%5Cfrac%7Bq_1q_2%7D%7Bd%5E2%7D%20%5C%5C%5C%5C%209%20%5Ctimes%2010%5E%7B-9%7D%20%20%3D%209%20%5Ctimes%2010%5E9%20%5Cfrac%7Bq%5E2%7D%7B%287%20%5Ctimes%2010%5E%7B-4%7D%29%5E2%7D%20%5C%5C%5C%5C%20q%5E2%20%3D%204.9%20%5Ctimes%2010%5E%7B-25%7D%20%5C%5C%5C%5C%20%20q%20%3D%207%20%5Ctimes%2010%5E%7B-13%7D%20%5C%20C)
Hence the charge on each of the equally charged drops of hairspray willl be 7 × 10 ⁻¹³ C
