Particles of charge Q1 = +62 µC, Q2 = +45 µC, and Q3 = -80 µC are placed in a line (Fig. 16-37). The center one is 0.35 m from each of the others. Calculate the net force on each charge due to the other two.(adsbygoogle = window.adsbygoogle || []).push({});

I have found the forces between Q1 - Q2, Q2 - Q3, and Q1 - Q3.

Here is my work for Q1 - Q2:

[tex]F = kq1q2/r^2

F = (8.99e9)(62e6)(45e6)/(.35)^2

F = 2.05e26 N

[/tex]

I entered this Force value in for Q1

Force on Q1:

Magnitude

_______ N

Direction

right

up

left

down

and it marked me wrong, though I got the direction right. Am I not using the right force for Q1 or something? I am quite confused with this, any help would be very appreciated, thank you.
