Question

Consider the following statements:
P. The net moment of the rigid body is zero means that the distance between the force and rotational axis is zero.
Q. The main condition for a rigid body is that the distance between various particles of the body does not change.
Out of above statements, the correct combination is:

• A. P - True, Q - True
• B. P - True , Q - False
• C. P - False, Q - True
• D. P - False , Q - False

Answer 1

The correct option is C P - False, Q - True

The net moment of a body is zero does not mean that the distance between the force and the rotational axis is zero. This implies that moment caused by different forces get cancelled out.
