Three concurrent forces of the same magnitude are in equilibrium. What is the angle between the forces ? Also, name the triangle formed by the forces as sides
Options
- A30^ isosceles triangle
- B60^ equilateral triangle
- C120^ , 30^ , 30^ an isosceles triangle
- D120^ an obtuse triangle
Correct answer
B. 60^ equilateral triangle
Step-by-step solution
In N forces of equal magnitude works on a single point and their resultant is zero, then angle between any two forces is = 360^ N = 360^ 3 =120^ If these 3 vectors are represented by three sides of triangle, then they form equilateral triangle.
