What is the relationship between electric field strength and the force on a charged particle?

The relationship between electric field strength and the force on a charged particle is governed by the equation ( F = qE ), where ( F ) is the force acting on the charged particle, ( q ) is the charge of the particle, and ( E ) is the electric field strength. According to this equation, force is directly proportional to electric field strength, meaning that as the electric field strength increases, the force experienced by the charged particle also increases, provided that the charge remains constant.

This direct proportionality indicates that if you double the electric field strength while keeping the charge the same, the force will also double. This is key in understanding how charged particles behave in electric fields and is a fundamental concept in electrostatics. The correct answer reflects this essential relationship, emphasizing that any changes in the electric field strength will directly affect the force experienced by a charged particle.
