The location of a point on the .v-axis at which the net electric field due to these two point charges b is zero : 2L 3L 4L5 6L 3 / 10 23.The graph drawn between V are r for a non-conducting charged solid sphere of radius R for r < R will be : straight line parabola hyperbola None of these 4 / 10 24.Corona discharge takes place: at the surface of a conductor near the sharp points of a conductor outside the conductor at the centre of the conductor 5 / 10 25.The belt of a Vande Graaf generator gets charge by : corona discharge induction electrification None of these 6 / 10 26.Quantisation of charge implies: Charge does not exist Charge exists on particles There is a minimum permissible magnitude of charge Charge can’t be created 7 / 10 27.The conservation of electric charge implies that: Charge can’t be created Charge can’t be destroyed The number of charged particle in the universe is constant Simultaneous creation of equal and opposite charges is permissible 8 / 10 28.The number of electrons contained in one coulomb of charge is: 6.25 × 1018 5 × 1018 4 × 1018 3 × 1018 9 / 10 29.The unit of intensity of electric field is : metre/volt Joule/newton Coulomb/newton Newton/coulomb 10 / 10 Q.30 1 V equals to: 1 J 1 JC-1 1 CJ-1 1 JC Your score isThe average score is 25% LinkedIn Facebook Twitter VKontakte 0% Restart quiz
