Assertion Electric lines of force can never cross each other Reason Electric field at a point always superimposes to give one resultant electric field Assertion The magnetic field strength produced by a current carrying solenoid is independent of its length and cross sectional area Reason The magnetic field strength inside the solenoid is uniform Assertion Free electrons always keep on moving in a conductor even then no magnetic force acts on them in the magnetic field unless a current is passed through it Reason The average velocity of a free electron is zero Assertion To convert a galvanometer into an ammeter a small resistance is
