Two identical point charges are placed at a separation of l.P is a point on the line joining the charges, at a distance x from any one charge. The field at P is E. E is plotted against x for values of x from close to zero to slightly less than l. Which of the following best represents the resulting curve ?
- a)
- b)
- c)
- d)
Correct answer is option 'D'. Can you explain this answer?

At point P,
E=E1−E2 rightward
⟹E=(kq/x2)−(kq/(l−x)2) where k=1/4πϵo
⟹E=kq (l(l−2x)/x2(l−x)2)
From graph we can see that it can't be straight line and E=0 at x=l/2
At x=0 ,,E→∞ and at x=l, E→−∞
Hence, from the shown graphs the correct answer is (D).

Yes the coorect option is d as the distance increases from first charge E decreases and at the midpoint E=0, and there after it increases but due to the charge placed at opposite end
