why electric field due to a solid sphere is in rad

Question

why electric field due to a solid sphere is in radial direction. Two rings each of radius r are coaxially placed a distance r metres apart.if q1 and q2 berespectively the chargesuniformly spread on the rings the work done in moving a charge q from the centre of one ring to that of other

1st part :you can probably say that it is a symmetrical figure so the tangential opposite components ancel each other .2nd part: it is one of the questions from irodov. you can do it as follows(only steps)1.find the potential of the ring intially that is KQ/(R^2+r^2)it will be due to the two above rings .2.find the final potential ,which will be again due to two rings .3.work done=pot energy final-pot energy initial.
