Answer:
The maximum electric field
Explanation:
From the question we are told that
The diameter is
The magnetic field of the cylinder is
The frequency is
The radial distance is
This magnetic field can be represented mathematically as
The initial magnetic field is the average between the variation of the magnetic field which is represented as
Then is the amplitude of the resultant field is mathematically evaluated as
The electric field induced can be represented mathematically as
At maximum electric field
Answer:
The new period is 16 s
Explanation:
The period of a simple pendulum is given by
Where is the period
is the length of the string
is the acceleration due to gravity
2π is constant
For the first experiment,
Then,
....... (1)
For the second experiment
Hence,
becomes
Then,
....... (2)
Since 2π is constant and
The same pendulum is used for the second experiment, then is also constant.
∴ is constant for both experiment.
Hence, we can equate equations (1) and (2) such that
Then,
Hence, the new period is 16 s
