The question i am stuck on and am unable to find anything in my notes about (although i can't find my notes from tuesday however we seem to have covered the topic on friday and maybe just not finished it off in time) is ...
Two isolated spherical conductors one with radius R and one with radius 3R, each carrying a positive charge Qo. The spheres are brought together and then separated again, find the charge on each sphere.
from what i can think they would act as one surface and the charge would evenly distribute over the whole surface, then i would work out the surface area of each sphere seperately and take a ration and then spread the charge of 2Qo over each sphere and give my answer in terms of Qo?
then a little more difficult
if a small charged sphere is brought into contact with another identical sphere which has no charge then separated by 10cm the force between them is 9x10^-3N what was the original charge on the first sphere
it relates to my answer from before, if i am right with what i said above, would i work out the difference between the 2 and work out the respective charges, then add them together to get the charge originally on the first?
any and all help greately appreciated, thanks
