A Charge of 2 C is moved in an electric field from infinity to two points P And Q.If the work done in bringing the charge to point P is 14 J and in bringing it to that point Q is 18 J,Calculate the potential difference between the two points P and Q.

I assume work done to bring 2 C charge from infinity to point P is 14 J and work done to bring 2 C charge from infinity to point Q is 18 J
 
potential difference between two points is the difference of workdone to bring a unit charge from infinity to the respective point. 
 
hence potential diffrence between P and Q is (18-14)J/(2C), which is equal to 2 Volt. Point Q is at higher potential

Plssss answer..... Assertion: Magnetic field lines never intersect each other. Reason: If they intersect, then at the point of intersection, the compass needle would point towards two directions, which is not possible.
