# An electron of mass $m_e$ initially at rest moves through a certain distance in a uniform electric field in time $t_1$. A proton of mass mp also initially at rest takes time $t_2$ to move through an equal distance in this uniform electric field. Neglecting the effect of gravity the ratio of $\large\frac{t_2}{t_1}$ is nearly equal to:

## 1 Answer

Neglecting the effect of gravity the ratio of $\large\frac{t_2}{t_1}$ is nearly equal to:$\bigg( \frac{m_p}{m_e} \bigg)^{1/2}$
Hence B s the correct answer
