Explanation:
We can understand better this situation using a diagram with the forces acting on it.
In the attached image we can see that when the gravity center is bouncing outside from the area of the pedestal, the object will be out of balance and will fall.
Answer:
Angular velocity (w) = 8.86 rad/s
Explanation:
Angular velocity (w) =
g= 9.81 m/s
R= 0.5
hi (initial depth) = 0.5m
Hence= = 8.86 rad/s
Answer:
a) E = 0
b)
Explanation:
The electric field for all points outside the spherical shell is given as follows;
a)
From which we have;
E = 0/A = 0
E = 0
b)
By Gauss theorem, we have;
Therefore, we get;
The electrical field outside the spherical shell
Therefore, we have;
