A charge Q is uniformly distributed on the circumference of circular ring of radius R and it is enclosed within a charged spherical shell of same radius R such that center of the sphere touch the circumference of the ring.Find the total electric flux through the surface of hollow sphere(shell)?

SINCE THE RING IS ENCLOSED INSIDE THE SPHERE, SUCH THT THE CENTRE OF THE SPHERE TOUCH THE CIRCUMFERENCE OF THE RING, U CAN VISUALISE OR ASSUME A RING ON THE SPHERE COPLANER WITH THE CHARGED RING. NOW IF U DRAW THE DIAGRAN U WILL SEE THT THE PORTION OF THE RING INSIDE THE SPHERE IS SUTENDING AN ANGLE 2pie/3 rad AT THE CENTRE OF THE SPHERE.NOW SINCE THE LINEAR CHARGE DENSITY OF THE RING IS UNIFORM U CAN CALCULATE THT Q/3 CHARGE IS INSIDE THE SPHERE SINCE ONE - THIRD PORTION OF RING IS INSIDE THE SPHERE.THEREFORE THE FLUX PASSING THROUGH THE SPHERE WILL BE

 

plz... vote if satisfied or u can ask for more details.
