Question

Forces exerted by a uniform electric field on an electron having mass $ m_{e} $ and proton of mass $ m_{p} $ are represented as $ F_{e} $ and $ F_{p} $ respectively are related as

• A. $ F_{p}=F_{e} $
• B. $ \frac{F_{e}}{F_{p}}=\frac{m_{e}}{m_{p}} $
• C. $ \frac{F_{e}}{F_{p}}=\frac{m_{p}}{m_{e}} $
• D. $ \frac{F_{e}}{F_{p}}=\frac{m_{e}^{2}}{m_{p}^{2}} $

Answer 1

Answer: (A)

The force $(F)$ on charge $q$ due to electric field strength $E$ is
$F = q E$
Here, $E$ is uniform, hence
$ F_p = F_e $
