Class 12 Physics Multiple Choice Questions
Class 12 Physics Multiple Choice Questions 1) A system containing two equal and opposite charges separated by a finite distance is called as: Electric flux Electric dipole Electric field None of the above Answer: (b) Electric dipole Explanation: The dipole moment has two charges with the separation distance between them. The two charges are +q and -q, while the separation distance is 2l. It means that the net charge on an electric dipole is 0. 2) Which of the following statements about the electric field lines is incorrect? Electrostatic field lines cannot intersect. Electrostatic field lines cannot form closed loops. Electrostatic field lines must be normal to the surface of the conductor. Electrostatic field lines cannot originate from the positive charge. Answer: (d) Electrostatic field lines cannot originate from the positive charge. Explanation: Electrostatic field lines can originate only from the positive charge and terminates at the negative charge. It cannot or...
