As we have learnt,

 

when Charged Particle at rest in uniform field -

Force and acceleration

F= QE

a= \frac{QE}{m}

 

 

- wherein

m - mass

Q - charge

E - Electric field strength.

 

  

a = \frac{F}{m}=\frac{eE}{m}


Option 1)

\frac{e^2}{m}

Option 2)

\frac{E^2e}{m}

Option 3)

\frac{Ee}{m}

Option 4)

\frac{mE}{e}
