1.e problem statement, all variables and given/known data
Two positrons and two protons are kept on the four corners of a square of side a. Positrons are kept at vertices A and C and protons are kept at B and D. let q denote the charge on both positron as well as the proton. So what is the kinetic energy of the positron and proton respectively after a long time ?
I used the work energy theorem ie
Change in k.e. = wk. done
And work done = kq²/a
First I calculated the kinetic energy of the positron due to all the 3 charges. I got the equation 2*kq²/a + kq²/root 2.
But the value that came after simplifying this equation did not match with the answer given in my book...
