Two connected charges of +q and -q respectively are a fixed distance AB apart in a non uniform electric field whose lines of force are shown in the figure. The resultant effect on the two charges is
Answer & explanation
Correct answer: option 4
The electric field line show that there is negative charge present nearby the positive charge.
Now, F1>F2 because of non-uniform electric field.
∴ there will be a force in the plane of paper.
Next there will be a torque to align the charge. i.e. to move +ve charge downwards and −ve charge upward which will result of a torque normal to the plane of the surface.
