JEE Mains · Physics · STD 11 - 6. system of particles and rotational motion
A force of \(40\, N\) acts on a point \(B\) at the end of an \(L-\) shaped object, as shown in the figure. The angle \(\theta\) that will produce maximum moment of the force about point \(A\) is given by
- A \(\tan \theta = \frac{1}{4}\)
- B \(\tan \theta = 2\)
- C \(\tan \theta = \frac{1}{2}\)
- D \(\tan \theta = 4\)
Answer & Solution
Correct Answer
(C) \(\tan \theta = \frac{1}{2}\)
Step-by-step Solution
Detailed explanation
To produce maximum moment of force line of action of force must be perpendicular to line \(AB\).
