Options

• The electric potential has a maximum magnitude at C and the electric field has a maximum magnitude at A.

• The electric potential has a maximum magnitude at D and the electric field has a maximum magnitude at B.

• The electric potential at A is zero and the electric field has a maximum magnitude at D.

• Both the electric potential and electric field achieve a maximum magnitude at B.

Answer 1

Both the electric potential and electric field achieve a maximum magnitude at B.
