1) A positively charged particle is released from rest in an uniform electric field. The electric potential energy of the charge a) remains a constant because the electric field is uniform b) increases because the charge moves along the electric field. c) decreases because the charge moves along the electric field. d) decreases because the charge moves opposite to the electric field. 2) Equipotentials at a great distance from a collection of charges whose total sum is not zero are approximately a) Spheres b) Planes c) Paraboloids d) Pllipsoids 3) A conductor with a positive charge a) is always at +ve potential. b) is always at zero potential. c) is always at negative potential. d) may be at +ve, zero or -ve potential. 4) If a unit positive charge is taken from one point to another over an equipotential surface, then a) work is done on the charge. b) work is done by the charge. c) work done is constant. d) no work is done. 5) Which of the following options is correct? In a region of constant potential a) the electric field is uniform. b) the electric field is zero. c) there can be charge inside the regiofi. d) the electric field shall necessarily change if a charge is placed outside the region. 6) The maximum electric field that a dielectric medium of a capacitor can withstand without breakdown of its insulating property is called its a) Polarisation b) Capacitance c) Dielectric strength d) NOTA
