Question

An electron having charge e and mass m is moving in a uniform electric field E. Its acceleration will be (A) (e2/m) (B) (E2 e/m) (C) (e E/m) (D) (m E/e)

When charge q is moving in uniform electric field E, then its acceleration a=(q E/m) (constant). Hence, acceleration of an electron is a=(F/m)=(e E/m).

Q. An electron having charge $e$ and mass $m$ is moving in a uniform electric field $E$ . Its acceleration will be

$\frac{e ^{2}}{m}$

$\frac{E ^{2} e}{m}$

$\frac{e E}{m}$

$\frac{m E}{e}$

When charge $q$ is moving in uniform electric field $E$ , then its acceleration $a = \frac{qE}{m}$ (constant). Hence, acceleration of an electron is $a = \frac{F}{m} = \frac{e E}{m}$ .
