Want this question answered?
it will occure if the charge is positive, other wise it will move to opposite direction.
yes,the direction of electric force on a charge is tangent of field lines.
Electric charge is a scalar quantity. It doesn't have direction, any more than the charge for a pack of gum or the charge for burglary has direction. Sorry.
It has plenty of direction. The direction of the electric field at any point in it is the direction of the force that would be felt by an infinitesimally small positive charge placed at that point.
positive charge

positive charge
Yes. The electric field in physics is represented by a vector, it has three components governing the field strength in the up-down, left-right and forward-backwards directions.

Current is a scalar if it is given as a scalar - such as 5A. There is no direction connected with this. If it is referenced to a voltage - 5A at 30 degrees lagging the voltage - then it is a vector quantity.
In an alternating current (AC) circuit, the electric charge periodically reverses direction at a certain frequency. This is in contrast to a direct current (DC) circuit, in which charge flows in one direction only.
We define the "direction"of an electric field to be the direction of the force it exerts on a positive test charge placed in the field. So if there is some charge inside a shell, the field outside the shell points outward if the charge inside is positive, and inward if the charge inside is negative.
Direction and electric flux density. Representing an electric field (and this works with other fields also) with lines is a sophisticated and time honored tradition. The density of lines in any region of space is proportional to the strength (magnitude) of the field in that region of space. The direction of the field is along the direction of the line at each position on each of the lines. In such a graphical representation the field direction goes out from positive charge and in towards negative charge and the visualization usually has some indication of the sign of charge or direction of the field to give the information about direction of the vector field represented by the field lines.
The electric field lines are directed away from a positive charge and towards a negative charge so that at any point , the tangent to a field line gives the direction of electric field at that point.
