no they wont as in the case of cunductor it will flow to the outer suface, thus conductor will hold lesser charge!!!!

no they do not have same charge.
in conductors charge resides on the surface. therefore , q=4*pi*r*r
in an insulator charge may reside inside i.e volume distribution of charge - q=4*pi*r*r*r
Bad news is that time always flies,
Good news is that u r the pilot.

yesterday is history,
tomorrow is a mystery,
today is a gift and that is why it's called "the present".

Hi divalli, for insulator its q= (4/3)  r3.
 
 
Above explnation seem to be correct
A paradox is an argument that starts with apparently acceptable assumptions and leads by apparently valid deductions to an apparent contradiction. Since logic admits no contradictions, either the apparently acceptable assumptions are not acceptable, or the apparently valid
deductions are not valid, or the apparent contradiction is not a contradiction. A paradox moves us to reexamine the argument until we find out what is wrong.
