B= 0.6 T (- z direction)
The resultant force on the proton given as
F= m a
For uniform motion acceleration should be zero.
F = 0
Electric filed should be apply in the negative x direction.
Answer:
the distance between interference fringes increases
Explanation:
For double-slit interference, the distance of the m-order maximum from the centre of the distant screen is
where is the wavelength, D is the distance of the screen, and d the distance between the slits. The distance between two consecutive fringes (m and m+1) will be therefore
and we see that it inversely proportional to the distance between the slits, d. Therefore, when the separation between the slits decreases, the distance between the interference fringes increases.
