Answer with Explanation:
We are given that
Density=
A(4m,2m,4m) and B(0,0,0)
y=1 m
a. Linear charge density=
Let a point P (0,1,4) on the line of charge and point Q (0,1,0)
Therefore,
Distance AP=
Distance,BQ=
Electric field for infinitely long line
Therefore, potential
b.Electric field at point B
Unit vector r=
Therefore,
An alpha particle is identical to a helium nucleus ... 2 protons, 2 neutrons. <em>(1)</em>

Answer:
Constructive interference
Explanation:
Here, the medium is same, same wavelength, same frequency, same amplitude and same direction of propagation.
Let the intensity of waves be I which is same for both
The formula for the net intensity is
where, Ф be the phase difference
So,
Here, IR is maximum so the interference is constructive in nature.
