Answer:
So electric field between the plates will be equal to
Explanation:
We have given potential difference between accelerating plates = 24 KV = 24000 volt
Distance between the plates d = 1.5 cm = 0.015 m
We know that potential difference is given by V = Ed, here E is electric field and d is distance between plates
So
E = 1600000 N/C =
So electric field between plates will be equal to
Answer:
(a)
(b)
Solution:
As per the question:
Mass of the object, m = 1.30 kg
Length of the rod, L = 0.780 m
Angular speed,
Now,
(a) To calculate the rotational inertia of the system about the axis of rotation:
Since, the rod is mass less, the moment of inertia of the rotating system and that of the object about the rotation axis will be equal:
(b) To calculate the applied torque required for the system to rotate at constant speed:
Drag Force, F =
