Homework Statement
Particle A with a charge of 45 micro Coulombs is located on the x-axis at a point -11 cm from the origin. Particle B with a charge of 41 micro Coulombs is located on the y-axis at a point +68 cm from the origin. What is the magnitude of the electrostatic force that Particle A exerts on Particle B? (Answer in Newtons.)
Homework Equations
Coulomb's Law: Fe=ke(q1q2/r^2)
The Attempt at a Solution
(8.99x10^9)((45x10^6)(41x10^6))/11^2
(8.99x10^9)((41x10^6)(41x10^6))/2(68^2)
Not sure what to do next or if this is even right so far. I think I have to do something w/ the x and y components and find the degree of the angle, which I'm not sure how to do.
