Balanced and Unbalanced ForcesQuiz - Solve & Score
Q1. A crate is pushed from one side by Rohan with 60 N and from the directly opposite side by Sameer with 25 N. What is the magnitude of the net force on the crate?
- A.60 N
- B.85 N
- C.35 N
- D.0 N
Answer: C. 35 N
The two forces act along the same line in opposite directions, so the net force is their difference: 60 N - 25 N = 35 N. Because the forces are unequal the force is unbalanced.
Q2. a worker shoves a trolley eastward with 90 N while a helper pushes it westward with 40 N along the same line. How large is the resultant force acting on the trolley?
- A.90 N
- B.130 N
- C.50 N
- D.0 N
Answer: C. 50 N
The two forces act along the same line in opposite directions, so the net force is their difference: 90 N - 40 N = 50 N. Because the forces are unequal the force is unbalanced.
Q3. On a loaded sledge, one man applies 120 N to the right and a second man applies 70 N to the left. What single net force does the loaded sledge experience?
- A.120 N
- B.190 N
- C.0 N
- D.50 N
Answer: D. 50 N
The two forces act along the same line in opposite directions, so the net force is their difference: 120 N - 70 N = 50 N. Because the forces are unequal the force is unbalanced.
