# Q.Non-coplanar concurrent forces are those forces which

• AMeet at one point, but their lines of action do not lie on the same plane
• BDo not meet at one point and their lines of action do not lie on the same plane
• CMeet at one point and their lines of action also lie on the same plane
• DDo not meet at one point, but their lines of action lie on the same plane
Correct Answer : (A)

Meet at one point, but their lines of action do not lie on the same plane

Hints :

Non-coplanar concurrent forces are those forces which Meet at one point, but their lines of action do not lie on the same plane.
