An infinitely long circular rod of radius r contains a uniform charge density \rho . use guass's law to find the electric field for r> r and r< r .

this is an electrodynamics exercise, i hope you can give as much detail as possible

as technology advances, new experiments often expose problems in accepted theories. c

hope i

uranium fissions/breaks up giving out energy and neutrons

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
