What is the direction of electric field intensity on a Gaussain surface around a point charge ?

What is the direction of electric field intensity vector vecE ?

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: If there is a system of two unequal point charges of any polarity then there is one and only one point in space around it where the electric field intensity is zero. Reason: The direction of electric field intensity at a point is away from the positive charge and towards the negative charge, along the line joining the charge and location where electric field intensity is to be calculated.
