Two infinte plates are in the (x,y,z) space. one in X=5 and the second in X=-5. they are charged with superficial density SIGMA. Between them there is a spatial density P. P=A*X^2(X is the variable and A is constant. out the space(for example=X=10 or x=-10) the Electric field is 0.(adsbygoogle = window.adsbygoogle || []).push({});

I have to find the expression for the field(for every x and x) between the plates. How do I do that?

The answer is E=(4/3)(∏)K*A(X^3)

Thanks
