Q: Which of the following options explain the Coplanar non-concurrent forces?
  • A. All forces lie in the same plane, but their lines of action pass through a single point
  • B. All forces do not meet at a point but lie in a single plane
  • C. All forces are parallel to each other, but not in the same plane
  • D. All forces do not lie in the same plane and their lines of action do not pass through a single point
Correct Answer: Option B - Coplanar non-concurrent forces:- The forces which do not meet at one point, but their lines of action lie on the same plane are known as coplanar non concurrent forces. Non-coplanar non concurrent forces:- The forces which do not meet at one point and their lines of action do not lie on the same plane are called non coplanar non-concurrent forces.
B. Coplanar non-concurrent forces:- The forces which do not meet at one point, but their lines of action lie on the same plane are known as coplanar non concurrent forces. Non-coplanar non concurrent forces:- The forces which do not meet at one point and their lines of action do not lie on the same plane are called non coplanar non-concurrent forces.

Explanations:

Coplanar non-concurrent forces:- The forces which do not meet at one point, but their lines of action lie on the same plane are known as coplanar non concurrent forces. Non-coplanar non concurrent forces:- The forces which do not meet at one point and their lines of action do not lie on the same plane are called non coplanar non-concurrent forces.
