yes, since the induced electric field is perpendicular to the path PQ, therefore work done is zero
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
