Explanation:
total answer is 119 km
this is the answer for the question
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,
I can't see the screw (if you'll pardon the expression), so I don't know a thing about it, and can't answer the question. There's no given information in the question.
could you please refries this
The distance is measured between the 'centers of mass',
or 'centers of gravity' of both objects. That's the point inside
the object where there's the same amount of mass in every
direction away from it.
If the object is something like a sphere, or a cube, or a uniform
wooden board, or anything "symmetrical", then the center of mass /
center of gravity is the actual center of the object. If the object has
some irregular shape, then it's harder to calculate or measure where
its center is.
