railway RRB JE (CBT I + CBT II) Mock Test 2024 Engineering Mechanics Equilibrium and Friction Equilibrium
Two forces of equal magnitude (= Q) act at an angle of θ to each other. The resultant of these forces will be:
1
\(2\ Q \cos \frac{\theta}{2}\)
2
2 Q cos θ
3
Q cos θ
4
\( \frac{Q}{2} \cos 2 \theta\)
