As per your syllabus, the TORQUE (moment of force) on a particle at position r due to force F is which vector product?
Aτ = F × r
Bτ = r × F
Cτ = r · F
Dτ = r + F
Answer & Solution
Correct answer: B. τ = r × F
Your syllabus: τ = r × F. Vector quantity, perpendicular to plane of r and F. Magnitude τ = r F sin θ.
