A physical quantity, electric field intensity has
Correct answer: C. direction along the electrostatic force.
- A. no direction.
- B. direction along the area of surface.
- C. direction along the electrostatic force.
- D. direction making an angle of 45o with force.
Explanation
Electric field intensity is defined as the electrostatic force experienced by a unit positive charge. Since force is a vector quantity, the electric field intensity is also a vector quantity, and its direction is the same as the direction of the electrostatic force.Therefore, the correct option is: * C) direction along the electrostatic force.

About Electric Field Intensity
Electric field intensity is the force acting per unit positive test charge, with direction set by the force on that charge. Work includes fields of point charges, vector superposition, field lines and the relation between field and electric potential. Field intensity must be distinguished from electric force and potential.
