Problem
A researcher accelerates two isolated particles, A and B, from rest through the same potential difference of 250 V. The particles have identical charge magnitude but different masses, as listed below:
• Particle A: charge +e, mass 3.34×10−27kg
• Particle B: charge +e, mass 1.67×10−27kg
After acceleration, the particles travel in regions where no additional forces act on them.
(a) Calculate the kinetic energy of each particle immediately after it has passed through the 250 V potential difference. Express your answers in joules.
(b) Determine the speed of each particle at that same moment. Show all steps clearly and include appropriate units.
(c) Identify which particle has the greater speed and provide a concise explanation that relates your numerical results to the roles of charge and mass in the energy conversion process.
