Q64. Consider a charge at the origin of 3- dimensional coordinate system. The flux of the electric field through the curved surface of a cone that has a height h and a circular base of radius R (as shown in the figure)is hQ REo OR )hEo (a) (b) (c) 2e
option b is correct means Q/2*epsilon... Ms, vaishali did right... you can make one more cone in opposite direction so that whole surface(first cone+new cone) is now closed...
but if the charge it some other position of cone, you can't do this method...

you can assume a second cone just below the given cone, such that it covers the given charge at centre. now flux through this closed arrangement is q/(epsilon). so the flux through...
