$1\mathrm{.}1$ Plot the Electric Field lines of two charges

Plot in python the $$Electric Field Lines$$ for the following configuration of charges:

q$0=1\mathrm{.}0$ C $$x$0=(1\mathrm{.}0,0\mathrm{.}0)$

q$1=1\mathrm{.}0$ C $$x$1=(1\mathrm{.}0,0\mathrm{.}0)$

$1\mathrm{.}2$ Plot the Electric Field lines of three charges

Plot in python the $$Electric Field Lines$$ for the following configuration of charges:

q$0=1\mathrm{.}0$ C $$x$0=(1\mathrm{.}0,0\mathrm{.}0)$

q$1=1\mathrm{.}0$ C $$x$1=(1\mathrm{.}0,0\mathrm{.}0)$

q$2=3\mathrm{.}0$ C $$x$1=(0\mathrm{.}0,1\mathrm{.}0)$
