Answer:
0.0979 N/c
Explanation:
Electric field, E is given as a product of resistivity and current density
E=jP where P is resistivity and j is current density
But the current density is given as
where I is current and A is area and
Substituting this into the first equation then
Given diameter of 0.259 cm= 0.00259 m and the radius will be half of it which is 0.001295 m
Answer:
30.95°
Explanation:
We need to define the moment of inertia of cylinder but in terms of mass, that equation say,
Replacing the values we have,
At the same time we can calculate the mass moment of intertia of cylinder but in an axial way, that is,
Finally we need to find the required angle between the fixed line a-a (I attached an image )
Replacing the values that we have,
