Calculate the magnitude and direction of the Coulomb force on each of the three charges shown in Figure P15.10.
thats 3 cm if its to small to see.
6.00 µC charge
1.50 µC charge
-2.00 µC charge
F = K|q1||q2|/r^2
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:
8.9875 x 10^9 (6 x 10^-6)(2 x 10^-6)/.05^2 (converted to m and C)
= 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)/.02^2 this completely got me the wrong answer and not sure where to start on this.
