أرجوكم تحلون لي هالمسألهـ


:shy_5new:


two parallel horizontal plates are spaced 0.60 cm a part in air . you introduce an oil droplet of mass 7.4 x 10^(-17) kg between the plates .
if the droplet carries five electronic charges and if there were no air buoyancy, you could hold the droplet motionless between the plates if you kept the potential difference between them at :
a-5.4V
b-27V
c-3V
d-0.54V
e-270V


بليز الله يخليكم تساعدوني بحلها
