28 Electric field between oppositely charged parallel conducting plates When two plane parallel conducting plates having the size and spacing as shown in the figure are given equal and opposite charges the field between and around them is approximately as shown while most of the charge accumulates at the opposite faces of the plates and the field is essentially uniform in the space between them there is a small quantity of charge on the outer surfaces of the plates and a certain spreadwing or fringing of the field at the edges of the plates As the plates are made larger and the distance between them diminished the fringing becomes relatively less This kind of arrangement is called capacitor Now if two plates are separated by a distance 3d and are maintained at a potential difference V then answer the following questions I i Capacitance of a parallel plate capacitor depends on a electric charge stored b electric field between the plates c potential difference applied d electrical permittivity of the medium between the plates ii If two protons are placed at points A and B respectively then which one will experience more force d A d B d a Proton at point A b Proton at point B c Proton at points A and B both experiences same force d None of the above 5 iii When both the protons are released then which one will gain more K E just before striking the negative ve plate a Proton released from point A b Proton released from point B c Proton released from points A and B will gain equal kinetic energy d No one will gain kinetic energy iv If one proton is moved from 1 A to B II B to C and III along ABCD then work done in cases I II and III respectively are a eED Zero eED b eED Zero Zero c eED eED Zero d eED eED Zero v Which property of electric field is shown by answer to III part of questions iv a Non conservative nature b Conservative nature c Dissipative nature
