Function electric_force_on_charge 

pub fn electric_force_on_charge(charge: f64, electric_field: f64) -> Option<f64>

Computes electric force using F = qE.

Returns None when either input is not finite or when the computed result is not finite.

Examples

use use_electromagnetism::electric_force_on_charge;

assert_eq!(electric_force_on_charge(2.0, 3.0), Some(6.0));
assert_eq!(electric_force_on_charge(-2.0, 3.0), Some(-6.0));
