Question
The resultant of two forces equal in magnitude is equal to either of two vectors in magnitude. Find the angle between the forces.(A) $60^{\circ}$(B) $45^{\circ}$(C) $90^{\circ}$(D) $120^{\circ}$
Step 1
The formula for the resultant $R$ of two vectors with an angle $\theta$ between them is given by \[R = \sqrt{F^2 + F^2 + 2F \cdot F \cdot \cos(\theta)}.\] Show more…

Two forces of magnitude F have a resultant of the same magnitude F. The angle between the two forces is (a) 45° (b) 120° (c) 150° (d) 60
The resultant of two forces, one double the other in magnitude, is perpendicular to the smaller of the two forces. The angle between the two forces is (a) $60^{\circ}$ (b) $120^{\circ}$ (c) $150^{\circ}$ (d) $90^{\circ}$
If two vectors are equal and their resultant is also equal to one of them. then the angle between the two vectors is (a) $60^{\circ}$ (b) $120^{\circ}$ (c) $90^{\circ}$ (d) $0^{\circ}$
