The net force that is applied to the airplane is 700 N to the right (Option B).
How to calculate the net force on the airplane?
The net force that is applied to the airplane is calculated by applying the following formula as follows;
F(net) = sum of the right forces - sum of the leftward forces
The sum of the rightward forces = 800 N
The sum of the left ward forces = 60 N + 40 N = 100 N
The net force that is applied to the airplane is calculated as;
F(net) = 800 N - 100 N
F(net) = 700 N to the right
Thus, the net force that is applied to the airplane is 700 N to the right
