Answer:
The period of the pendulum is
Explanation:
The diagram illustrating this setup is shown on the first uploaded image
From the question we are told that
The length of the rod is
The diameter of the ring is
The distance of the hole from the one end
From the diagram we see that point A is the center of the brass ring
So the length from the axis of rotation is mathematically evaluated as
Now the period of the pendulum is mathematically represented as
Answer:
Explanation:
give data:
inside diameter = 5.0 cm
charge q = 0.25 nC
Outside diameter = 15 cm
potential V at inside sphere is =
potential V at outside sphere is =
k is constant whose value is =
then potential difference between two point is
