Out of the following statements, concerning an electric field, which statement is not true ?
Correct answer: B. The electric field intensity at a point is numerically equal to the force exerted upon a charge placed at that point
- A. The electric intensity is a vector quantity
- B. The electric field intensity at a point is numerically equal to the force exerted upon a charge placed at that point
- C. An electric field is defined as a point in space at which an electric charge would experience a force
- D. Unit field intensity in the exertion of a force of one newton on a charge of one coulomb
Explanation
Electric field intensity is force per unit charge, E = F/q, so it equals the force only when the charge is 1 coulomb. Thus statement b incorrectly omits the division by charge.
