a) What is the y-component of the total electric field at P?
*the answer is not 3.10x10^6 N/C
b) Now let Q2 = Q1 =2.30 μμC. Note that the problem now has a symmetry that youshould exploit in your solution. What is the magnitude of the totalelectric field at P?
*the answer is not 1.53x10^8 N/C
c) Given the symmetric situation of the previous problem, whatis the magnitude of the force on an electron placed at point P?
*the answer is not 2.448x10^-11 N
