Along straight wire carries a 40.0 a current in the +x direction. at a particular instant, an electron moving at 1.0  107 m/s in the +y direction is 0.10 m from the wire. the charge on the electron is –1.6  10–19 c. what is the force on the electron at this instant?

Explanation:

Given that,

Current flowing in the wire, I = 40 A (+x direction)

Speed of the electron, (+y direction)

Distance from the wire, r = 0.1 m

Let F is the electric force on the electron. It is given by :

Here,

Here,

So, the force on the electron at this instant is . Hence, this is the required solution.
