The direction of the electric field due to a point charge at any point is along the line joining the charge and the point and away from the charge for a positive charge and towards the charge for a negative charge. g

true or false?

g. The statement is true.

Explanation:

As the electric field is defined as the force per unit charge, it is also a vector,  which acts along the straight line joining the point with the charge that produces the field, same as if there were a charge in this point.

By definition, the direction of the electric field, would be the one that would take a positive test charge (small enough not to change the charge distribution that produces the field), placed in the point where we can find the field value, so it will be away of the charge if the charge creating the field is positive and vice versa if the charge is negative.

real, smaller and upside-down.   so the answer should be b.

i think the answer would be reserve.
