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

  1. A30^ isosceles triangle
  2. B60^ equilateral triangle
  3. C120^ , 30^ , 30^ an isosceles triangle
  4. 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.
