Answer:
a
b
Explanation:
From the question we are told that
The amplitude is
The period is
The test weight is
Generally the radial acceleration is mathematically represented as
at maximum angular acceleration
So
Now is the angular velocity which is mathematically represented as
Therefore
substituting values
Generally this test weight is mathematically represented as
Where k is the spring constant
Therefore
substituting values
Answer:
the correct one is 2. the equipotential lines must be closer together where the field has more intensity
Explanation:
The equipotential line concept is a line or surface where a test charge can move without doing work, therefore the potential in this line is constant and they are perpendicular to the electric field lines.
In this exercise we have a charge and a series of equipotential lines, if this is a point charge the lines are circles around the charge, where the potential is given by
V = k q / r
also the electric field and the electuary potential are related
E =
therefore the equipotential lines must be closer together where the field has more intensity
