Answer:
Slit width is 0.109 mm
Solution:
As per the question:
Wavelength of the light,
Distance from the screen, D = 5.6 m
Bright band in the center, 2x = 8.1 cm
x = 4.05 cm
Now,
To calculate the slit width, w:
From the diffraction:
For small angle:
≈
Also
Thus
Substituting appropriate values in the above eqn:
w = 0.109 mm
Answer:
The second option.
When the current flows up the wire, the magnetic field flows out on the left side of the wire and in on the right side of the wire.
Explanation:
The first figure that I copy here with is the figure corresponding to this question.
The thumb is pointing upward.
The rule is that the thumb aims to the direction of the flow of current and the other fingers give the field lines.
The second figure that I attach is a free image from internet and it shows the direction of both the current and the fiedl lines.
So, the conclusion is that the current goes upward the wire and the field lines go out of the paper (screen) for the points to the left of the wire and in on the right side of the wire.
