Two identical point charges are placed at a separation of I. 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?

Dear student

Enet=Eq1-Eq2=kq(q1l-x2-q2x2)at x= 0, Enet is finite and positive...............(1)at x=l,Enet is finite and negative.....................(2)at x=l2, Enet is zeroand the graph should not be symmetric because values of 1 and 2 are not samethus, option c is correct 


Regards

since E=kq/x^2 . therefore E is inversely proportiona to x...
when x=0 , E=INFINITY  THEREFORE OPTION A IS RIGHT ANSWER....
