For example we will consider a parallel plate capacitor C = \frac{\varepsilon A}{d} thus , Capacity of a cacpacitor is inversly proportional to the separation d , so if we decrease the separation , capacitance will increase.

while third one is liner so field lines woluld be linear

while in figure one it has no perticular shape so perpendicular to every surface means filed line may be like that.

dear for circular or symmetrical it will outword towards the surgace and always perpendicular to the surface means in circle it follows by radius so it would be in radial direction

and how nearness increase capacity as C=QV. no distance is there ?????
- Like(2)
nearness will effect the experincing charge of both plates due to each other

in capacitor they should be near so they can feel each others filed lines or area of influence..... otherwise there would be no capacitor if we put them at large distance.....becuse now two opposite polarity not intrecting with each other
