Which of the following statements are correct?

(A) All of electrostatics is basically a consequence of Coulomb's law and the super position principle.
(B) A change producing the electric field is a test change.
(C) Electric and magnetic fields are regarded as physical entities.
(D) In water molecule centres of positive changes and negative changes do not coincide.
(E) Electrostatic field lines cannot form closed loops.

Choose the correct answer from the options given below:

(A), (C), (D) and (E) Only

The correct answer is Option (1) → (A), (C), (D) and (E) Only

(A) True, The fundamental principles of electrostatics derive from coloumb's force and superposition principle. They explain the forces between charges and the resulting electric fields.

(C) True, electric and magnetic fields are real physical entities that can store energy and exert forces on charges.

(D) True, In a water molecule ($H_2O$), the centers of positive and negative charge do not coincide, resulting in dipole moment.

(E) True, Electrostatic field lines always start on positive charge and end on negative charges and cannot form closed loops because the electric field lines is conservative.
