Calculate the magnitude and direction of the Coulomb force on each of the three charges shown in Figure P15.10.

http://www.webassign.net/sf5/p15_10.gif

thats 3 cm if its to small to see.

6.00 µC charge

Magnitude

1.50 µC charge

Magnitude

-2.00 µC charge

Magnitude

2. Relevant equations

F = K|q1||q2|/r^2

3. The attempt at a solution

I tried this problem and it said i was incorrect but within 10% to the answer and that my rounding is off or something.

this is what i did:

(converted to m and C)

8.9875 x 10^9 (6 x 10^-6)(2 x 10^-6)/.05^2

.10785/.05^2

=43.14 N

That looks correct but it is saying im off. It say that im within 10% to the answer. Can anyone look at this and tell me what im doing incorrectly?

For the other 2 I am not sure what to do, but i gave it a try

for 1.5uC i did

K(1.5 x 10^-6)(2 x 10^-6)/.02^2this completely got me the wrong answer and not sure where to start on this.
