The electric field intensity at a point in vacuum is equal to

Identify the correct statement1) Electric field intensity is the negative gradient of scalar electric potential function. 2) Electric field projects normal to an equipotential surface and project from a higher potential surface towards lower potential surface. 3) Both 1 and 2 are correct4) None

The amplitude of electric field intensity on the surface of a good conductor is E0. The amplitude of the field at a depth equal to skin depth is Select one:a. 0.18E0b. 0.36E0c. zerod. 0.72E0

an electric field is vertically acting upwards a small body of mass 1gm and charge -1uC is projected with a velocity 10m/s at an angle 45° with horizontal. its horizontal range is 2m then the intensity of electric field is : (g=10m/s)

For the volume charge density ρ, the divergence of the electric field intensity will be equal to Select one:a. ε0 ρv  b. ρv / ε0   c.  ε02ρv d. ρv  / ε02

The intensity of electric field at a point between the plates of a charged capacitorIs directly proportional to the distance between the platesIs inversely proportional to the distance between the platesIs inversely proportional to the square of the distance between the platesDoes not depend upon the distance between the plates
