Amount of Force

Explanation:

Before Firing cannonball the system is in equilibrium and Total Force acting on it is zero.
After firing cannonball, cannonball and cannon experience equal force (Newton's Third Law of Motion)
After firing the total force also has to be zero.

Initially #F=0#

Finally #vecF_"cannonball"+vecF_"cannon"=0#
#vecF_"cannonball"=-vecF_"cannon"#

The amount of Force are equal but they act in opposite direction.
