Which of the following statements are correct ? (A) Electrostatic field lines form closed loops. Choose the correct answer from the options given below: |
(A) and (D) only (A), (B) and (D) only (B), (C) and (E) only (C), (D) and (E) only |
(C), (D) and (E) only |
The correct answer is Option (4) →(C), (D) and (E) only (A) Electrostatic field lines form closed loops. Incorrect — electrostatic field lines start from positive charges and end at negative charges, so they do not form closed loops. (B) In an electric dipole, the direction from charge to q is the direction of the dipole. Incorrect — the dipole direction is from negative charge to positive charge, not the reverse. (C) Water molecule is an example of polar molecule. Correct — water has unequal charge distribution due to its bent shape, making it polar. (D) The electric field due to a uniformly charged thin shell is zero at some points inside the shell. Correct — in fact, the electric field is zero at all points inside the shell. (E) Electrostatic force is conservative in nature. Correct — the work done by electrostatic force is independent of the path taken. |
