Three particles are fixed in place and have charges q1=q2=2q>0 and q3=q<0. What are the magnitude and direction of the net electric field at point P due to the particles?

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
