Non-coplanar non-concurrent forces are those forces which

ক

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

খ

Do not meet at one point and their lines of action do not lie on the same plane

গ

Do not meet at one point but their lines of action lie on the same plane

ঘ

None of the above

Which is the correct statement about law of polygon of forces?

ক

If any number of forces acting at a point can be represented by the sides of a polygon taken in order, then the forces are in equilibrium

খ

If any number of forces acting at a point can be represented in direction and magnitude by the sides of a polygon, then the forces are in equilibrium

গ

If a polygon representing forces acting at a point is closed then forces are in equilibrium

ঘ

If any number of forces acting at a point can be represented in direction and magnitude by the sides of a polygon taken in order, then the forces are in equilibrium

Concurrent forces are those forces whose lines of action

ক

Lie on the same line

খ

Meet at one point

গ
