Answer:

The electric force on an electron in this field $3.2\times 10^{-15}\ N$ .

Explanation:

We have,

Electric field of along the +x-axis is $2\times 10^4\ N/C$

It is required to find the electric force on an electron in this field. The electric force acting on the particle is given by :

$F=qE$

q is charge of electron

$q=-1.6\times 10^{-19}\ C$

So,

$F=1.6\times 10^{-19}\times 2\times 10^4\\\\F=3.2\times 10^{-15}$

So, the electric force on an electron in this field $3.2\times 10^{-15}\ N$ .
