I keep getting “Coulomb's law” questions wrong in Electrostatics. What's the trap?
ignoring that like charges repel and unlike attract when assigning direction.

What does “Electric field” actually mean in Electrostatics, and why does it matter for NEET?
the force per unit positive charge, E = F/q; field lines point away from positive charges.

I keep getting “Electric field” questions wrong in Electrostatics. What's the trap?
treating field (a vector) and potential (a scalar) as the same thing.

I keep getting “Electric potential” questions wrong in Electrostatics. What's the trap?
thinking zero field means zero potential (or vice versa).
