Uniform electric fields are regions where electric forces remain constant in magnitude and direction. In this scenario, the field points vertically upward, impacting the proton's vertical motion. This uniformity simplifies calculations, as the force exerted on the proton is constant, leading to a consistent vertical acceleration.
- The electric field's magnitude is denoted by , serving as a central value in our calculations.
- In this field, a positively charged proton experiences a force , where is the charge of the proton.
This force acts vertically, altering the proton's vertical velocity, which is crucial in determining its downward maximum mid-journey and the time it takes to return to its original height. A uniform field thereby provides a straightforward framework for understanding electric force impacts on motion.
