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.
I don’t know how to fill this out since there is no picture attached.
Answer:
The number of charges is 1.25 × 10¹⁰
Explanation:
Current is the amount of charge flowing through a conductor per second. The formula for current (I) is given as:
I = Q/t
Where Q is the charge flowing in coulombs and t is the time taken in seconds.
Given that I = 2.0 nA = 2 × 10⁻⁹ A and t = 1 sec
I = Q / t
Q = It = 2 × 10⁻⁹ × 1 = 2 × 10⁻⁹ C
Since each charge = 1.6 x 10⁻¹⁹ C, therefore:
The number of charges = 2 × 10⁻⁹ C / 1.6 x 10⁻¹⁹ C = 1.25 × 10¹⁰
In the single-slit experiment, the displacement of the minima of the diffraction pattern on the screen is given by
(1)
where
n is the order of the minimum
y is the displacement of the nth-minimum from the center of the diffraction pattern
is the light's wavelength
D is the distance of the screen from the slit
a is the width of the slit
In our problem,
while the distance between the first and the fifth minima is
(2)
If we use the formula to rewrite
, eq.(2) becomes
Which we can solve to find a, the width of the slit:
