In Figure P10.18, all surfaces experience friction. Is the magnitude of the horizontal component of the force exerted by \(A\) on \(B\) greater than, equal to, or less than the magnitude of the horizontal force exerted by \(\mathrm{A}\) on \(\mathrm{C}\) if the system of blocks is \((a)\) moving at a constant velocity to the right and \((b)\) accelerating to the right due to an external force exerted on B?
