Convert force in newtons to external impulse | bevy rapier 3D

[Nigless]

im trying to implement buoyancy, but result force is too strong.

let drag_force = -velocity.normalize() * (velocity.length().powf(2.0) * liquid.density * area * 0.5);

let buoyant_force = -config.gravity * liquid.density * volume;

commands.entity(entity).insert(ExternalImpulse::at_point(
        buoyant_force + drag_force,
        intersection_center,
        collider_position + center_of_mass,
));

Have you tried using a
"constant" force instead ? https://docs.rs/bevy_rapier3d/latest/bevy_rapier3d/dynamics/struct.ExternalForce.html#structfield.force ; "impulse" is usually used to represent sudden pushes.
