 =0[1-r2/a2] ,for r<=a
and rho=0 for r>a
a:radius for the sphere
Find the electric field at a distance 'r' from the center,when
a) r>a
b)r<a
c)Find the value of r for which the intensity of electric field is maximum inside the sphere.
my answers(don't know if my answers are correct or incorrect)
a) 0
b) E=r(a2-r2)epsilon(not)/3a2
c) r=a/ 3

yarr Karthik shouldn't we have to take a spherical gaussian surface to make calculations easy
and can u plzz tell me if my answers are correct or not..
thanks for your support

Oops... sorry. I did take a spherical gaussian surface. I made a typing mistake there. Rest is fine.

jasbir, I have considered a sphere that encloses the required volume. Choosing the gaussian surface is upto us.
