Ответ:
The angular frequency of oscillation of the mass is 11 rad/s.
Explanation:
Given that,
Charge = 2μC
Radius R₁= 8 cm
Radius R₂ = 16 cm
Angular frequency = 22 rad/s
We need to calculate the angular frequency of oscillation of the mass
The electric field produced along x axis
The force on the mass is
For,x<<R
Now, using centripetal force
Put the value of F in equation (I)
We know that,
For, r<<R
Here,
The ratio of angular frequency
Put the value of
Hence, The angular frequency of oscillation of the mass is 11 rad/s.
