Subonit Answer Save Progress Prectice Anather Vension lectric charge can accumulate on an airplane in flight. You may have observed needle-shaped metal extensians on the wing tips and tai of an airglane. Ther purpose is to allaw arge to leak off before much of R accumulates. The electric field around the needle s much larger than the fed around the body of the arplane and can becom e lare e o g roduce dielectric breakdown of the ar, discharging the airplane. To model this process, assume that two charped spherical conductors are connected by a long conducting wire and charge of 66 0 uc s placed on the conOne shere, representing thby f the srplane, hes a radus er 6.0, nd the ethe,rhe de dius of 2.00 cm (a) What is the electric potential of each sphere?

Explanation / Answer

6. given uniformly charged insulated rod

l = 12 cm

q = -8.5 uC

and

pi*r = l

r = l/pi

at point O

Vo = k*q/r = k*q*pi/l

hence

Vo = 8.98*10^9*(-8.5*10^-6)*pi/0.12 = -1.998314727 MV
