Question:
Block pressed against wall by force \(F\). Find incorrect statement.
Block pressed against wall by force \(F\). Find incorrect statement.
Show Hint
Any force not passing through CM produces torque.
Updated On: Apr 23, 2026
- friction force = mg
- \(F=N\)
- \(F\) does not apply torque
- \(N\) does not apply torque
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Torque depends on line of action of force.
Step 1: Check forces
Normal force acts at wall $\Rightarrow$ can produce torque
Step 2: Incorrect statement
Saying \(N\) produces no torque is wrong Conclusion: (D)
