Three coplanar concurrent forces of magnitudes 7 N, 24 N and 25 N are in equilibrium. What is the angle between the 7 N and 24 N forces?
Options
A. 180°
B. 120°
C. 60°
D. 90°
Explanation
For equilibrium, the resultant of the 7 N and 24 N forces balances the 25 N force. Since 7²+24²=25², the first two forces are perpendicular, so the angle between them is 90°.
