Does anyone realise a thing in Physics

What is the equation of the electric field lines ,

for two same magnitude charges ?

I think it requires the knowleges of differential equations so i post it here .

Thanks!

depends on the volume and shape of the charges

if the charges are just a point you dont need differential equations

calculate the 2 vectorial field and add them together
