Best answer

Correct option  (c) Electricfield

Explanation:

 Electric field = [(Electric potential) / length] = (V/m);

 Force = mass × acceleration, work = Force × displacement

 V = (W/Q) = [(F ∙ S) / Q] = [(ma ∙ s) / Q] = [(m ∙ a ∙ s) / It]…..

  [as (F = m × a), (W = F × S), (Q = I × t)]

   ∴ V = {([M1L1T–2][L]) / [AT]} = [M1L2T–3A–1]

  Electric field = [(potential) / (length)] = ([M1L2T–3A–1] / [L]) = [M1L1T–3A–1
