The net force of the system provided is F = 20 N.
The cue ball moves with a force of +70 N to the left, and four balls move with a force of -50 N to the right,
According to the information given in the question
We have,
F = 20 N in a leftward direction.
Cue ball moving towards left with a force of 70 N
Four-ball moving towards right with a force of -50 N
So,
The net force,
F = (-50) + 70
F = 20 N
The SI unit of Force is Newton and the symbol of newton is N.
