In summary, an electric field is a region in space where an electric charge experiences a force, created by other electric charges. The relationship between electric field and electric force is that the field is a measure of the strength of the force and has the same direction. The strength of an electric field is calculated by dividing the force acting on a charge by the magnitude of the charge itself. It is affected by the magnitude and location of the charges and the distance between them. The direction of an electric field determines the direction of the force on a charged particle, with particles of the same charge experiencing a repulsive force and particles of opposite charge experiencing an attractive force.

1. What must the charge (sign and magnitude) of a 1.45 g particle be for it to remain stationary when placed in a downward directed electric frield of magnitude 650N/C? also What is the magnitude of an electric field in which the electric force on a proton is equal in magnitude to its weight.

What do I do?

Compute the gravitational force and the electric force and set them equal and opposite, right? What else would you do?
 
1.

What is an electric field?

An electric field is a region in space where an electric charge experiences a force. It is created by other electric charges and can be represented by lines of force that show the direction and strength of the field.

2.

What is the relationship between electric field and electric force?

Electric field and electric force are closely related. The electric field is a measure of the strength of the force that an electric charge will experience at a certain point in space. The direction of the electric field is the same as the direction of the force that would act on a positive charge placed in that field.

3.

How is the strength of an electric field calculated?

The strength of an electric field is calculated by dividing the force acting on a charge by the magnitude of the charge itself. This results in a quantity known as the electric field intensity, measured in Newtons per Coulomb (N/C).

4.

What factors affect the strength of an electric field?

The strength of an electric field is affected by the magnitude and location of the charges creating the field. It also depends on the distance between the charges, with stronger fields occurring when the charges are closer together.

5.

How does the direction of an electric field impact the motion of a charged particle?

The direction of an electric field determines the direction of the force that will act on a charged particle placed in that field. If the particle has the same charge as the source of the field, it will experience a repulsive force and move away from the source. If the particle has the opposite charge, it will experience an attractive force and move towards the source of the field.
