Question

Which expression gives the acceleration of an electron in an electric field?

Options

• \[a=\frac{I}{A}\]

• \[a=\frac{eE\tau}{m}\]

• \[a=-\frac{eE}{m}\]

• \[a=\frac{ne^2\tau}{m}E\]

Answer 1

The electron’s acceleration is \[a=-\frac{eE}{m}\]. Here, \[e\] is the electronic charge and \[m\] is the mass of an electron.
