Calculate the electric field at the center of the circle:

Question

anonymous · Answer

can the circle be the sphere?  say @CShrix

anonymous · Answer

@lall I'm not sure. It does not specify sphere. I would assume that the field inside a sphere is 0, given that the material is conductive.

anonymous · Answer

read one of the statements in the middle, there is written that the 2 half circles are separated by thin insulator thus there is no charge conductance b/w the  2 half circles....

thus if the circles are charged then the charges shold lie on the boundary of the half circles so that the 2 half circles have an electric field uniformly on the centre...

anonymous · Answer

could it be so?

anonymous · Answer

i think u just need to apply the formula for electric field for the individual charges for half of the radius each

anonymous · Answer

Wouldn't that just yield the normal equation:
$$E=\frac{kQ}{r^2}$$
