It is mùlti correct


Is C and D?

Ans is acd

A is not making any sense to me.

Can you share your approach ?

I checked direction using its standard formula.
I think for any straight line path it will 0.

I got option d but not getting a and c. Can you share your approach in detailed?

the electric field lines will be circular ,ie will form clockwise closed loops in this case
