Which of the following best expresses the principle of superposition as applied to linear restoring forces in oscillatory motion?
(a) The net restoring force equals the arithmetic mean of the individual restoring forces acting simultaneously.
(b) The net restoring force equals the algebraic sum of all individual restoring forces acting simultaneously.
