Answer:
100.49N
Explanation:
First we must know that the normal force acts in the vertical direction;
The force required to push to the right and left acts in the horizontal direction;
Sum of force along the horizontal Fx = 50N - 60 N = -10N
Force along the vertical Fy = 100N
The net force on the object is calculated as;
F = √(Fx)² + (Fy)²
F = √(-10)² + (100)²
F = √100 + 10000
F = √10,100
F = 100.49N
Hence the net force on the object is 100.49N
