If the forces are equal, at a distance equidistant it is not possible to act a pair on the body since both torques cancel each other. Being of the same magnitude and in the opposite direction, the sum of the torques will be zero.
Answer:
Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.
Explanation:
The distance from the central band to the first bright band is given by
where is the wavelength of light (or any particle),
is the distance to the screen, and
is the slit separation.
From this equation we see that, by increasing the wavelength , increasing the distance from the screen
, and decreasing the slit separation
, we increase the distance between the first bright band and the central band.
Therefore, the 2nd choice "<em>Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.</em>" is correct.
