Answer:
Angular velocity is same as frequency of oscillation in this case.
ω = x
Explanation:
- write the equation F(r) = -K with angular momentum <em>L</em>
- Get the necessary centripetal acceleration with radius r₀ and make r₀ the subject.
- Write the energy of the orbit in relative to r = 0, and solve for "E".
- Find the second derivative of effective potential to calculate the frequency of small radial oscillations. This is the effective spring constant.
- Solve for effective potential
- ω = x
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;
