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

`120^(@), 30^(@), 30^(@)` an isosceles triangle

D

`120^(@)` an obtuse angled triangle

Verified by Experts

The correct Answer is:

B

If N forces or vector of equal magnitude, act on a point and resultant is zero

Then angle between any two forces or vector –
`= (360)/(N)= (360)/(3)= 120^(@)`
