Equipotential lines are always perpendicular to electric field lines. This is because equipotential lines represent points in a field with the same electric potential, so moving along an equipotential line does not change potential. Thus, the electric field lines, which point in the direction of the greatest change in potential, intersect equipotential lines at right angles.

In which direction is the electric field on the cylindrical Gaussian surface oriented?
The electric field on the cylindrical Gaussian surface is oriented perpendicular to the surface, pointing outward or inward depending on the charge distribution inside the surface.
You turn an electric dipole end for end in a uniform electric field.How does the work you do depend on the initial orientation of the dipole with respect to the field?
The work done by you to turn the electric dipole end for end in a uniform electric field depends on the initial orientation of the dipole with respect to the field. If the dipole is initially oriented such that its positive and negative charges are parallel to the electric field, then no net work is done as the electric field does not do any work on the dipole as the electric field lines do not transfer any energy. On the other hand, if the dipole is initially oriented such that its positive and negative charges are perpendicular to the electric field, then work is done by you to turn the dipole as the electric field exerts a force on the charges in the dipole in opposite directions, causing them to move in opposite directions. As a result, you have to do work to move the charges and turn the dipole.
What is the relationship between electric potential and electric field in a given system?
In a given system, the electric potential is directly related to the electric field. The electric field is the rate of change of electric potential with respect to distance. In other words, the electric field points in the direction of decreasing potential.
What is a radial electric field?
A radial electric field refers to an electric field oriented radially outward or inward from a central point or line. In the context of physics or engineering, it is often used to describe the electric field configuration in certain systems or devices, such as electric motors or charged particles moving along a radial path.
What is the relationship between the electric field (E) and the rate of change of the electric potential (V) with respect to the distance (r), as described by the expression e dv dr?
The relationship between the electric field (E) and the rate of change of the electric potential (V) with respect to the distance (r) is described by the expression E -dV/dr.

What is the relationship between the electric potential and electric field according to the equations V kq/r and E kq/r2?
The relationship between electric potential (V) and electric field (E) is that the electric field is the negative gradient of the electric potential. This means that the electric field is the rate of change of the electric potential with respect to distance. The equations V kq/r and E kq/r2 show that the electric field is inversely proportional to the square of the distance from the charge, while the electric potential is inversely proportional to the distance from the charge.
Which force field can accelerate an electron but never change its speed?
I would say a magnetic field. When an electron enters a magnetic field that is oriented perpendicular to its path of travel it causes the electron to loop in a circle. While the speed stays the same the velocity is constantly changing due to the circular motion. Hence same speed but undergoing an acceleration.
Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
If you use 10 joules of work to push 1 coulomb of charge into an electric field its voltage with respect to its starting position is?
10 voltage
What is the relationship between the electric field equation and voltage in an electric field?
The electric field equation describes the strength and direction of the electric field at a point in space. Voltage, on the other hand, is a measure of the electric potential difference between two points in an electric field. The relationship between the electric field equation and voltage is that the electric field is related to the gradient of the voltage. In other words, the electric field is the negative gradient of the voltage.
What is the area around an electric charge which is strongest closest to the charged particle?
It's the electric field.
