    Given the arrow there appears to be a fourth charge which is off the side of the paper.

    Ignoring that you have failed to notice that the distance is in NANO METRES ( 10 ^ -9 metres)

    Finally your arithmetic is wrong. Even with this correction your calculation is incorrect.

    What you SHOULD have done is shown US your work. I am experienced at finding errors and misconceptions. But there is nothing to find if you don't show us. ( my value has 2.15 in it not 2.68)
