It is required an infinite work. The additional electron will never reach the origin.
In fact, assuming the additional electron is coming from the positive direction, as it approaches x=+1.00 m it will become closer and closer to the electron located at x=+1.00 m. However, the electrostatic force between the two electrons (which is repulsive) will become infinite when the second electron reaches x=+1.00 m, because the distance d between the two electrons is zero:
So, in order for the additional electron to cross this point, it is required an infinite amount of work, which is impossible.

Answer with Explanation:
We are given that
Force acts on a pebble= N
Position vector= m
a.We have to find the resulting torque on the pebble about origin.
Torque=
Substitute the values then we get
Torque=N-m
By using
b.
Torque about point (2,0,-3)
N-m
