- 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.

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.
Do electric or magnetic fields point away from positive charges?
Electric fields point away from positive charges, while magnetic fields do not have a specific direction with respect to positive charges.
In an electromagnetic wave, in what direction do the electric and magnetic fields point towards each other?
In an electromagnetic wave, the electric and magnetic fields are perpendicular to each other.
What is the difference between positive and negative electric fields?
Positive electric fields point away from positive charges and towards negative charges, while negative electric fields point towards positive charges and away from negative charges. In both cases, the direction indicates the direction that a positive test charge would move if placed in that field.
What is converging mirror?
A converging mirror is a type of mirror that bulges outward and curves inward, also known as a concave mirror. These mirrors are curved inward and can converge light rays to a single focal point. They are commonly used in telescopes, microscopes, and makeup mirrors.
Do yaw bearings theeth point outward or inward?
Outward
Do yaw bearings' point outward or inward?
On some yaw bearings the teeth point outwards, while on others they are turned inwards.

What makes front tires tilt inward and point outward?
The alignment adjusting settings. If you are not sure, get an alignment , cheap and your tires will wear better

Positive electric fields point away from positive charges and towards negative charges, while negative electric fields point towards positive charges and away from negative charges. In both cases, the direction indicates the direction that a positive test charge would move if placed in that field.
The electric field of a point charge always points away from the charge?
If the given point charge is of positive one then the field points away from the charge. This is because we define the field at a point as the FORCE acting on unit POSITIVE charge. Like charges have to repel and hence the direction. If, other wise, the point charge is negative then electric field due to this negative charge would be towards the negative and not away from it.

Do electric field lines radiate outward like spokes on a wheel?
Only from a point charge, or from one with spherical symmetry.
Is it possible for an electric field to exist at point A in empty space?
Yes, it is possible for an electric field to exist at point A in empty space. Electric fields can exist even in the absence of matter, as they are created by the presence of electric charges.
