MCQ

Consider the following two statements A and B and identify the correct choice
(A) The torques produced by two forces of couple are opposite to each other.
(B) The direction of torque is always perpendicular to plane of rotation of body.

A
A is true but B is false.
B
A is false but B is true
C
Both A and B are true
D
Both A and B are false

✓

Answer

A is false but B is true

Explanation:

The direction of torque is always perpendicular to plane of rotation of body as a cross product is in perpendicular plane to r and F vectors and the torques produced by two forces of couple are in same direction to each other.
