COMEDK 2023 Evening Shift | Electrostatics Question 14 | Physics

An electron and a proton having mass $$m_e$$ and $$m_p$$ respectively, initially at rest, move through the same distance '$$s$$' in a uniform electric field '$$E$$'. If the time taken by them to cover that distance is $$t_e$$ and $$t_p$$ respectively, then $$t_e / t_p$$ is equal to:

$$ \sqrt{\left(\frac{m_p}{m_e}\right)} $$

$$ \sqrt{\left(\frac{m_e}{m_p}\right)} $$

$$ \frac{\sqrt{\left(m_e\right)}}{m_p} $$

$$ \frac{m_e}{m_p} $$
