Enter the electric field strength (N/C) and the charge point (C) into the Calculator. The calculator will evaluate the Charge Force. 

Charge Force Formula

CF = E*q

Variables:

  • CF is the Charge Force (N)
  • E is the electric field strength (N/C)
  • q is the charge point (C)

To calculate Charge Force, multiply the electric field strength by the charge point.

FAQs

What is the importance of calculating charge force in electric fields?

Calculating charge force is crucial for understanding the interaction between charged objects and electric fields. It helps in the design and analysis of electrical and electronic devices, ensuring they operate safely and efficiently.

Can charge force be negative?

Yes, charge force can be negative. The direction of the force depends on the nature of the charge (positive or negative) and the direction of the electric field. A negative force indicates that the force is acting in the opposite direction of the defined positive direction.

How does the electric field strength affect the charge force?

The electric field strength directly affects the charge force. A stronger electric field exerts a greater force on a charged particle. The relationship is linear, as shown by the formula CF = E*q, meaning the charge force is proportional to the electric field strength.

What units are used to measure charge force, electric field strength, and charge point?

Charge force is measured in Newtons (N), electric field strength is measured in Newtons per Coulomb (N/C), and charge point is measured in Coulombs (C).
