The quantity ½ E0E2 has the significant of
Correct answer: C. Energy/ volume
- A. Energy/farad
- B. Energy/ coulomb
- C. Energy/ volume
- D. Energy/volt
Explanation
The dimensions of the expression is M L-1 T-2 , which are also the dimensions of Energy/Volume½ 𝜺 0E^2𝜺i s the permittivity of free space with unit Fm^-1E is electric field strength with unit Vm^-1So the unit of ½ 𝜺 0E^2 can be simplified as follows.

About Electric Field
An electric field is the force experienced per unit positive test charge, with the field of a point charge given by E = kQ/r² and directed away from positive charges or toward negative charges. Questions involve field lines, superposition and force on a charge, while electric field must be distinguished from electric potential.
