Question

"The work per unit of charge required to move a charge from a reference point to a specified point, measured in joules per coulomb or volts. The static electric field is the negative of the gradient of the electric potential." comments are given below ,select the correct one

• A. Statement is correct
• B. Statement is incorrect
• C. Comment on electric field is not correct
• D. Only comment on electric potential is not correct

Answer 1

The correct option is A Statement is correct

The given statement is correct. Volt or Joules per Coulomb are SI unit of Potential (V) i.e, work done per unit charge to move a charge from a reference point to a certain point.
And electric field E is negative of the gradient of electric potential (V) i.e, $E=\frac{-dV}{dr}$
