Question:
Which one of the following force does not act on a cyclist when he/ she bends on a horizontal turn?
Which one of the following force does not act on a cyclist when he/ she bends on a horizontal turn?
Show Hint
Forces are "pushes or pulls." Torque is a "twist" resulting from those forces.
Updated On: May 13, 2026
- Weight (Mg)
- Centrifugal force ($Mv^{2}/r$)
- Friction (f)
- Torque ($\tau$)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
When a cyclist takes a turn, they interact with forces that provide stability and the necessary centripetal acceleration.
Step 2: Meaning
Weight acts downward, friction provides centripetal force toward the center, and centrifugal force acts outward in the rotating frame.
Step 3: Analysis
While individual forces like friction and normal reaction create moments, "Torque" is a resultant effect of forces acting at a distance from an axis, rather than a primary external force acting on the body like gravity or friction.
Step 4: Conclusion
Among the choices, torque is the parameter that is balanced (net torque is zero for stability) rather than an active external force like Mg or Friction. Final Answer: (D)
