Why does the electric force vectors around a positive charge point outwards and the electric force vectors around a negative charge point inwards?
the field lines should go away from positives and to negatives.
An electric field is a force field that surrounds electric charges and exerts a force on other charges placed within the field. It is a fundamental concept in physics and is used to describe the behavior of electrically charged particles.
An electric field is created by electric charges. Positive charges create an outward electric field while negative charges create an inward electric field. The strength of the field is determined by the magnitude of the charges and the distance between them.
The electric field and electric force are closely related. The electric field is the force per unit charge, meaning it describes the strength of the force experienced by a charged particle placed in the field. The direction of the electric field is the same as the direction of the electric force.
The electric field of a charge can be calculated using Coulomb's Law, which states that the electric field is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the charges. It can also be calculated using the formula E = kQ/r^2, where k is the Coulomb's constant, Q is the charge, and r is the distance between the charges.
Electric fields have numerous real-world applications, including powering electronic devices, creating lightning, and accelerating charged particles in particle accelerators. They are also used in medical imaging techniques, such as MRI machines, and in technologies like touch screens and wireless charging.
