Homework Equations


magnitude of the force is k(e^2)/(r^2)
k = 9 * 10^9 N*m^2/C^2
e = 1.6 * 10^-19C

The Attempt at a Solution


ke^2/(r^2) = (9*10^9 N * m^2/C^2)(1.6*10^-19C)^2/(.39^2 + .40^2)*10^-18m^2 = 7.38 *10^-10 N

Now find the two components .
 
ok this is what I got resultant y is y/sqrt(a^2+y^2)

then resultant x is x/sqrt(a^2+y^2)

this is what was stated in the book
