Function lorentz_force_scalar 

pub fn lorentz_force_scalar(
    charge: f64,
    electric_field: f64,
    velocity: f64,
    magnetic_flux_density: f64,
    angle_radians: f64,
) -> Option<f64>

Computes the scalar Lorentz-force convenience relation F = q(E + vB sin(theta)).

This helper is scalar-only and does not model the full vector Lorentz force.

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

Examples

use use_electromagnetism::lorentz_force_scalar;

assert_eq!(
    lorentz_force_scalar(1.0, 10.0, 2.0, 3.0, core::f64::consts::FRAC_PI_2),
    Some(16.0)
);
