The magnitude of the electric force between two protons is 2.30 10-26 n. how far apart are they?

The electric force between two charge objects is calculated through the Coulomb's law.

F = kq₁q₂/d²

The value of k is 9.0 x 10^9 Nm²/C² and the charge of proton is 1.602 x10^-19 C. Substituting the known values from the given,

2.30x10^-26 = (9.0 x 10^9 Nm²/C²) (1.602 x10^-19C) ²/d²

The value of d is equal to 0.10 m.
