Question

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 1. Which of the following best represents the resulting curve?

just wanted to let you know that I have a query regarding the same time as the way home from the you can come

Answer 2

Answer:

The electric field at P is E = kq[ 1(L - x)2 - 1x2] at x = 0, E = kq 1L2 at x = L, E ... 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? ... As E varies inversely with square of the distance so (D) represents the ...
