What is the equation for uniform electric fields?

F is the force, E is the electric field, and q is the charge.In summary, an object with a charge of -3.6μC and a mass of .012KG experiences an upward electric force equal to its weight due to a uniform electric field. The direction and magnitude of the field can be found using the equation F=Eq. If the charge is doubled while the mass remains the same, the new direction and magnitude of acceleration can also be determined using this equation. This is a non-calculus course and there is an equation for uniform electric fields: F=Eq.

Homework Statement



An object with a charge of -3.6μC and a mass of .012KG experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight. Find the direction and magn. of the field, and if the charge is doubled while its mass remains the same, find the direction and magn. of its acceleration.I really have no idea what this is. Is there an equation for uniform electric fields? I don't really even understand direction or magnitude of fields in this problem.

1. What is an electric field?

An electric field is a region in space where an electrically charged particle experiences a force. It is created by other charged particles and can either attract or repel other charged particles.

2. How is electric field strength measured?

Electric field strength is typically measured in units of volts per meter (V/m). This measures the amount of electric force per unit of charge at a particular point in space.

3. What is the relationship between electric field and force?

The force exerted on a charged particle in an electric field is directly proportional to the strength of the electric field and the charge of the particle. This relationship is described by the equation F = qE, where F is the force, q is the charge, and E is the electric field strength.

4. How does the direction of the electric field affect the force on a charged particle?

The direction of the electric field determines the direction of the force on a charged particle. If the electric field and the charge are in the same direction, the force will be in the same direction. If they are in opposite directions, the force will be in the opposite direction.

5. What are some practical applications of electric fields and forces?

Electric fields and forces have many practical applications, including powering electronic devices, generating electricity, and controlling the movement of charged particles in medical equipment. They are also essential in understanding the behavior of matter at the atomic and molecular level.
