Question

Three concurrent force of the same magnitude are in equilibrium. What is the angle between the forces? Also name the triangle formed by the forces as sides.
A. `60^(@)` equilateral triangle
B. `120^(@)`, equilateral triangle
C. `30^(@)`, an isosceles triangle
D. `120^(@)`, an obtuse angled triangle

Answer 1

Correct Answer - B
In `N` forces of equal magnitude works on a singel point and their resultant is zero then angle between any two forces is given
`theta=(360)/N= (360)/3= 120^(@)`
