Question

e force acting between two charged particles A and B is 5.2 × 10-5 newtons. Charges A and B are 2.4 × 10-2 meters apart. If the charge on particle A is 7.2 × 10-8 coulombs, what is the charge of particle B? (k = 9.0 × 109 newton·meters2/coulomb2)

Answer 1

The force acting between the particles is


`F=k (Q_(1)Q_(2))/(r^2)`
Then

`Q_(2)= (5.2 * 10^-^5 * 0.024^2)/( 9.0 * 10^9 7.2 * 10^-^8) =4.622 * 10^-^1^1C`
