The distance is 17 and the displacement is 1
Answer:

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.
