What is the direction of electric field due to a positive charge?

What is the direction of electric field due to a negative charge?

Assertion: Electric field intensity at a point due to a positive charge is always opposite in direction to electric field intensity due to negative charge, and it is independent to locațions of charges. Reason: The direction of electric field due to a point charge is away from the positive charge and towards the negative charge along the line joining the point charge and location where the electric field is to be calculated.
