1i think it sud b D,
since for any distance r,E is contant, thus to integrate over the whole gaussian sphere
we will have to simply multiply with 4Î r2.
then its coming D.
A static charge distribution produces a radial electrid field E = ae-br/ r2
where a nad b are constants.
total charge responsible for this field is ?
A) 0
B) 4Πε0ar
C) 4Πε0br
D) 4Πε0ae-br
I think it should be D . it is right?

3sri it shud not D because i think u have E=q/4∩ε0r2
this relation will not be possible because the charge distribution is not like charge distribution on a non conducting sphere because the field does not depend on the exponential terms for a sphere
the pbm can be solved by finding flux

1nobody trying this . well the answer is A . lekin mghe laga ki ans d hona chahiye . par woh to lim --->∞ le baite .I dunno why ? explaination needed
11sri dint get u what lem→∞ ???
but i feel ans should be D by mka genius solution
62See the answer you guys are jumping to is D..
but it is asked about the total charge ...
so you have to take r tending to infinity.
and there it will be zero...
So the final answre will be a) zero.
1we can do this by elemination.......it cant be B and C....they are dimensionally wrong.........and D is too scary......so ans is A.....thts all
62no akand.. but 99% of students will mark D as the correct choice for this one :)
