Which one of the following is not a vector quantity?
Correct answer: D. Electromotive force
- A. Electric field intensity
- B. Gravitational field intensity
- C. Magnetic induction
- D. Electromotive force
Explanation
The correct answer is electromotive force (EMF), which is a scalar quantity. Unlike vector quantities, EMF does not involve direction; it represents the energy provided per unit charge by a source. In contrast, electric field intensity, gravitational field intensity, and magnetic induction are vector quantities, all possessing both magnitude and direction.

About Addition of Vectors
Vector addition combines directed quantities using the head-to-tail, parallelogram and component methods. Work includes finding the resultant magnitude and direction for two or more vectors, resolving vectors into perpendicular components, and distinguishing vector addition from scalar addition, where direction has no role.
