An airplane flies horizontally at constant speed in a straightline direction. Its state of motion is unchanging. In other words

Alex_Xolod [135]

Answer:

sum of all forces on the air plane must be ZERO

So both forces must be of same magnitude

Explanation:

As we know that airplane is moving with uniform speed is horizontal plane is a straight line

so the motion of the air plane is uniform without any acceleration

So we will have

$a = 0$

acceleration must be zero

now by Newton's law

$F_{net} = 0$

$F_1 + F_2 = 0$

so sum of all forces on the air plane must be ZERO
