Answer #1

6)
c) V = 0 , E is not equal to zero

Becasue, at mid point the two wires produce same amount of elctric field in the direction of negative charged line.

so, net elctric field does not becomes zero.

at mid point positive charged wire produce positive potential and negative charged wire produce negative potential.

so, net potential becomes zero.

7)
b) V is not equal to zero, E = 0

Because, at mid point both wires produce equal ampuint of elctric field but in the opposite direction.

so, net electric field is zero.

at mid point Both wires produce same amount of positive potential. so, net potential does not become zero.
