An proton accelerated to a velocity of 3.81 × 10³ m/s will have more energy than an electron accelerated to the same velocity.

Question

Quizplus · Accepted Answer

A proton has a much greater mass than an electron, so when both are accelerated to the same velocity, the proton will possess more kinetic energy due to the kinetic energy formula $E_k = \frac{1}{2}mv^2$, where $m$ is mass and $v$ is velocity.
