I could try...☺

Answer 2

thanks

Answer 3

figure shows two point charges are placed symmetrically about the origin on the y-axis


a) calculate the electric field strength in point P and the origin

We loop the requirement that p must be fixed, and set p = (x, o) so that the point can be chosen freely on the x - axis.
b) calculate the field strength E in P as a function of x
c) calculate the possible extreme values of E
d) sketch E as a function of x
