Aif three forces acting upon a particle are represented in magnitude and
Bthree forces acting at a point will be in equilibrium
Cthree forces acting at a point can be represented by a triangle, each side being proportional to force
Dif three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two
Enone of the above
Correct answer
D. if three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two
Explanation
The correct answer is if three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two.
