Question

How do I find the magnitude of acceleration of an electron when I only know E?

Answer 1

To be given in quest ion

Electric field=E

$m=9.1\times10^{-31}kg$

$q=1.6\times10^{-19}culamb$

Particle is election

To be asked in question

acceleration=$a$

We know that

$F=ma \longrightarrow equation (1)$

$F=qE \longrightarrow equation (2)$

$equation (1)and eqution (2)$ are equal

$ma=qE$

$a=\frac{qE}{m}$

For partical is electron

Put value

$a=\frac{1.6\times10^{-19}E}{9.1\times10^{-31}} meter/sec^2$

$a= E\times1.758\times10^{-11}meter/sec^2$
