Calculate the length of arm of couple, if a force of 13 N produces a moment of couple of 14.3 Nm.
Assertion & Reasoning
- Assertion: The sum of the clockwise moments is equal to the sum of the anticlockwise moments.
- Reason: The principle of conservation of momentum is valid if the external force on the system is zero.
