Question) Calculate the work required to move an electron from A to B  along each of the three paths shown in figure 3.84. The electric field is in the positive y direction and has value E = 100 Vm-1 over all three paths. What is the potential difference between A and B. Please solve urgent.

Dear Student
Kindly find the answer of your asked query.

Potential difference between point A and B is given by:V=ABEdrV=13Edx+14Edy=1003-1+4-1=100×6=600 voltwork done = qV =- 1.6×10-19×600=-9.6×10-17 Joule
Hope this information will clear your doubt about electric field.
