a unifrom surface charge density 8sigma exists over the entire x-y plane except for acircular hole of radius of a point p(0,0,sqrt(3)) on the z-axis is found to be 2sqrt(x)(sigma)/(epsilon_(0)) ,Find the value of x. |

Answer» `rArr E_(net)=(sigma')/(2epsilon_(0))-(sigma)/(2epsilon_(0))(1-(z)/(sqrt(z^(2)+a^(2))))` `E_("net")=(sigma')/(2epsilon_(0)sqrt(z^(2)+a^(2)))` ` rArr E_("net")=((8sigma)sqrt(3)a)/(2epsilon_(0)(2A))=sqrt(12)(sigma)/(epsilon_(0))=2sqrt(3)(sigma)/(epsilon_(0))` `rArr x=3`
