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.

• A

  ${60}^0, \mathrm{equililateral} \mathrm{triangle}$

• B

  ${120}^0, \mathrm{equilateral} \mathrm{triangle}$

• C

  ${30}^0, \mathrm{an} \mathrm{isosceles} \mathrm{triangle}$

• D

  ${120}^0, \mathrm{an} \mathrm{obtuse} \mathrm{angled} \mathrm{triangle}$
