1.	A non-conductiong ring of radius ` -0.5 m` camies a total of ` 1. 11 xx 10 ^(-10) C` distributed non-unifrmly on its circumfernce producing an electric field ` vec E ` every where in space . The value of the line integral ` int_(t=infty)^(l=0) -vecE- vec Ed vec l (l=0)` being centre of the ring ) in volts is -A. ` +2`B. ` -1`C. ` -2`D. zero`
Answer» Correct Answer - A Potential at the centre of ring ` =- int_((l00))^(l-0) vec E. vec (Dl)` d ` - int_(l=infty)^(l=0) vec E. vec (dl) = (Kq)/R =2` volt.
