How do we determine the direction of the electric

We measured equipotentials, which are lines that connect points at which the magnitude of the electric field is equal. Can we tell anything about the direction of electric field lines with these measurements? Propose some additional measurements that would allow us to determine directionality.

you have two point charges half a meter apart. the charges have values of positive 1.0 microC and negative 2.0 microC. you want to move the charges apart to twice the distance between them, determine the amount of work needed just need to make sure i understood the question correctly and i followed through with the right method my answer that i got was 18 x 10^-3N

The best description of electric potential energy is the amount of energy … a) required to accelerate a particle to infinity from rest. b) consumed to stop a particle in motion. c) necessary to bring a particle from infinity, at rest, to its current location. d) transferred per unit of charge per second.

The figure below shows a dipole in a uniform electric field. If the dipole is released from rest, in which direction will it initially rotate? It won't rotate at all since the net force is zero. Counterclockwise The entire dipole will move to the right without rotation. Clockwise
