Question 1
One person pushes a motor car with a force of 150 N, and another pushes a different point on it with 200 N in the same direction. What is the resultant force?
The right answer is the one marked above.
350 N. When two forces are applied to an object in the same direction the resultant is their sum: 150 N + 200 N = 350 N.
50 N is the difference, which applies only when the forces oppose. The forces act at different points, but the direction is the same, so they add.
