1. two point charges q1 and q2 with a combined charge of 20 micro coulombs are placed 3m apart. If one repels the other with a force of 0.075N calculate;
the value of q1 and q22. k=8.987x10^9
F=kxq1xq2/r^2
E=kQ/r^2
E=f/q3. I've tried to work out the charge by working out the electric field strength with respect to one charge, then using the E=f/q and rearranging for q, this gave a value of
q1=3.755x10^-6
I then tried to sub this into coulombs force and rearrange for q2 but the value was faar too high.
I then tried to the same method and subtracting q1 the combined charge, but I'm certain this is not the method
Any help would be greatly appreciated
