A potential difference is applied between a conducting sphere and a conducting plate C'plus" on the sphere and "minus" on the plate). The dimensions of the plate are much larger than the distance between sphere and plate. A, point positive charge. is moved from P?int 1 to point 2 parallel to the plate. Is any work dono In the process?

If A is the area of each plate, charge on it is q and potential difference is V then the distance between the parallel plate capacitor is

An electric dipole is positioned between a pointlike charge and a uniformly charged conducting plate. III which direction will the dipole move?

(a) Find the potential difference between the plates of a parallel plate capacitor of capacitance 5muF if a charge +800muC is placed on one plate and- 200muC on another plate. (b) The charege given to plate are as shown. The capacitance between the adjacent plates is C . find the charge on outer surface of plate 3 , and potential difference between plate 1 and 2 . (c) If A is area of each plate and d is separation between adjacent plates, find the charge supplied by battery. (d) Five idential capacitor plates each of area A are arranged such that adjacent plates are at a distance d apart. the plates are connected to a source of emf V as shown. what is the magnitude and nature of charge on plates 1 and 3 respectively?

Into the region of space between the plates of a parallel-plate capacitor there Ilies (a) an electron and (b) a negatively charged ion with a velocity directed parallel to the plates. Both the electron and the ion have rec.eived their initial kinetic energy by passing the same potential difference U_0 and the potental difference across the capacitor is U. The distance between the plates is d. Which of the two particles will travel a greater distance before hitting the positively charged plate if both fly into the capacitor at a point that is exactly in the middle of the distance between the plates?

Force between two conducting large plates , with charges Q and Q/2 as shown in the figure, is (Area of each face of plate =A)
