Homework Statement
Four point charges of equal magnitude q = 6.4 X 10-19 C are placed at the corners of a square with side length a = 10 cm. Calculate the electric field at P, the center of the square, if q1 and q4 are positive and q2 and q3 are negative. (Use GUESS method.) Answer E = 3.26 X 10-6 N/C
Homework Equations
E=Fe/q E=kQ/r2 Fe=kq1q2/r2 Q=Ne F=ma
k=9.0E9
e=1.6E-19
The Attempt at a Solution
Q=Ne
Q=1*1.6E-19
9E9*1.6E-19/(.10^2)
And now I'm confused...I don't know what steps to follow, can anyone help?
