COMPREHENSION

n charges , all of same magnitude are placed at the n corners of a geometrical structure or object (eg.triangle,cuboid,tetrahedron,parallelogram etc.).At the centre of the structure potential is V and the field is E.It should be noted that n is ODD here.Answer the given questions.MORE THAN ONE CORRECT OPTIONS are there. 

<I>

(i) If V=0 then E0 or may be E=0

(ii) If V=0 then always E=0

(iii)If V=0 then always E0

(iv) If V0 then always E=0

(v) If V0 then always E0

(vi) If V0 then  E=0 or may be  E0

<II>

(i)If E=0 then V=0 or may be  V0

(ii)If E=0 then always V=0

(iii)If E=0 then always V0

(iv)If E then V=0 or may be V0

(v)If E0 then always V=0

(vi)If E0 then always V0
