Can a sphere of radius 1cm hold a charge of 1 coulomb?

Asked by DELFIN BIJU 23rd July 2013, 10:07 PM
Answered by Expert
the electric field that would be generated by 1C on a sphere of radius 0.01m on the surface of the sphere
 E = kq/r^2
=(9*10^9)/(1* 10^-4)
=9*10^13 V/m
the dielectric strength of air is about 3*10^6 V/m
so electric fiels generated by this sphere of charge will cause the air molecule to break downand nuteralise much of the sphere"s charge. hence answer is no.
