Explanation:
Formula to calculate the electric field of the sheet is as follows.
E =
And, expression for magnitude of force exerted on the electron is as follows.
F = Eq
So, work done by the force on electron is as follows.
W = Fs
where, s = distance of electron from its initial position
= (0.570 - 0.06) m
= 0.51 m
First, we will calculate the electric field as follows.
E =
=
= 0.259 N/C
Now, force will be calculated as follows.
F = Eq
=
=
Now, work done will be as follows.
W = Fs
=
=
Thus, we can conclude that work done on the electron by the electric field of the sheet is .
The momentum of an object is the product between the mass m of the object and its velocity:
The truck in our problem has momentum equal to
and a mass of
so, if we re-arrange the previous formula, we can use these data to find the velocity of the truck:
