Homework Statement
3 charges are arranged in the diagram below. their magnitudes are:
q1=2.5*10^-17C
q2=3.0*10^-17C
q3= 3.5*10^-17
calculate the direction and magnitude of q1
Homework Equations
F=kq^2/r^2
The Attempt at a Solution
well, i used f=kq^2/r^2, the charge of q3= (9*10^9)(3.5*10^-17)^2/(0.5)^2= 1.2*10^-17
q2=(9*10^9)(3*10^-17)^2/(0.50)^2= 3.24*10^-17N
im unable to find the angle of q1, how would i solve it really confused, i know you can use cos law but angle unknown, thank you
