My brain has been shocked by this problem dealing with charges and Coulombs law :(
This is what I did...
F = k*q1*q2/r^2
F = [ (8.99 * 10^9)(4.9 * 10-9)(6.0 * 10^-9) ] / (0.295)^2
F = 0.000000264 / 0.087025
F = 0.0000003034
F = 3.034 * 10^-7 N
F = k*q1*q3/r^2
F = [ (8.99 * 10^9)(4.9 * 10-9)(3.0 * 10^-9) ] / (0.295)^2
F = 0.000000132 / 0.087025
F = 0.0000001519
F = 1.519 * 10^-7 N
Resultant: √ (3.034 * 10^-7)^2 + (1.519 * 10^-7)^2 =√ ( 1.1488262 * 10^-13) = 3.39 * 10^-7
I got it wrong though :(
Please help
