24no rohit not that way........
Charge density is different but uniform on both sides of hemisphere.
Find the force exerted on lower by the upper hemisphere.
I need the approach. I have the answer

it also may be the case that My result is for condutor(general) and ur result is for specific sphere
1I dunno :)
My physics teacher seconded the formula.
But I don't trust him much. So nishant sir or kaymant sir might help us
24hmm...so how to know who is rite ???
nishant sir plz help here.....
24WHat I have found by searching..its given that electrostaic pressure is 2πσ2ε0
1Read this somewhere...
This question uses the concept of electrostatic pressure.
If a spherical surface is given a charge and has surface charge density σ,
and is flexible then it tries to expand due to the charge supplied. The
sphere behaves as if it is under stress.
The electrostatic pressure is given by σ22ε0
If the charge densities are different,
The electrostatic pressure is given by σ1σ12ε0
Thus, according to the question force
force exerted by the upper hemisphere on the lower hemisphere is
σ1σ1πR22ε0
1Yes sir, this is the question..
The answer is σ1σ2πR22ε0
1i think u will have to apply f=kqq/r2 n den do it..:)...think man think...
24@iota..I misintrepretted the queston.i solved for volume charge distribution ..that too equal...[3][3]
if u want that soln..i cna give..maybe it will give u an idea
