Choose the correct statements from the following:
A. The total charge in any isolated system remains constant.
B. When some charge is transferred to a conductor, its stays at the same place without getting distributed over the entire surface.
C. One Coulomb of negative charge is the total charge of $6.25 × 10^{18}$ electrons.
D. Electric field is a scalar field.
E. Permanent dipole means that the dipole moment $\vec P$ exists irrespective of external electric field $\vec E$
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A, C and E only
(A) This is a consequence of the law of conservation of charge, which states that charge can neither be created nor be destroyed.
(C) The charge of 1 electron, $q=-1.6×10^{-19}C$
$⇒\frac{1C}{1.6×10^{-19}C/electron}=6.25×10^{18}electrons$
(E) The dipole moment is intrinsic to the structure of the molecule or the system and does not depend an external influence.
