Electric charge can accumulate on an airplane in flight. you mayhave observed needle-shaped metal extensions on the wing tips andtail of an airplane. their purpose is to allow charge to leak offbefore much of it accumulates. the electric field around the needleis much larger than the field around the body of the airplane and, can become large enough to produce dielectric breakdown of the air, discharging the airplane. to model this process, assume that twocharged spherical conductors are connected by a long conductingwire and a charge of 22.0 µc isplaced on the combination. one sphere, representing the body of theairplane, has a radius of 6.00 cm, and the other, representing thetip of the needle, has a radius of 2.00 cm.(a) what is the electric potential of eachsphere? r = 6.00 cmvr = 2.00cmv(b) what is the electric field at the surface of each sphere? r = 6.00 cmv/m directionaway from the spheretoward the spherer = 2.00 cmv/m directiontoward the sphereaway from the spheredirections are toward and away from sphere
