can anyone help me out here? Three equal charges 5.1uC are located in the xy-plane, one at (0 m, 29m), another at (53m, 0m), and the third at (39m, -60 m). Find the magnitude of the electric field at the origin due to these three charges. Use k=8.99e9 Nm^2/C^2. Answer in units of N/C. thx.....dont u just love the bbs?
something about kq/d^2 is the force for each one. obviously, find the magnitude in each direction for the one at 60, 39 or whatever and add up the magnitudes, square em, add em, square root em, etc etc. is that how you do it. is that coulomb's rule or is that kq1q2/d^2 which is the force between to charges.
ya it has something to do with coulombs rule, we've just never seen a problem like this one. can anyone work it out?
Jerinrulz: a hint. First, find the distance from each of those points to the origin. When you do that it will make the problem much simpler.
Now just use the euqation f4p gave you earlier. You know d because you just calulated it. You know k b/c you're professor told you what to use. You know q because that's the charge given. So now use that equation for all three charges, and then add the results. That will give you the total field expereinced at the origin.
