Homework Statement
In the figure below, a right triangle, determine the magnitudes of the
a. Net e-field at p (assume a proton is placed at p)
b. Net electrostatic force at P
c. Net electrostatic potential at P
let q = 1.70 x 10^-8, R = 78cm and P is halfway between Q1 and Q3
Red dot is P
A^2 + B^2 = C^2 C = Sqrt(78^2+78^2)= 78sqrt(2)
Homework Equations
F= (K|q1q2|)/R^2
E= (k|q|)/ R^2
PE = (kq1q2)/R
The Attempt at a Solution
I just had a question about this problem, Since a proton is at the center, would Q1 and Q3 just cancel out since there are repelling one another and are the same charge?
If that is true would i just solve everything for the two point charges, proton and Q2 since i know what R would be between the two?
