Explanation:
The energy of the mass must be conserved. The energy is given by:
1)
where m is the mass, v is the velocity and h is the hight of the mass.
Let the height at the lowest point of the be h=0, the energy of the mass will be:
2)
The energy when the mass comes to a stop will be:
3)
Setting equations 2 and 3 equal and solving for height h will give:
4)
The angle ∅ of the string with the vertical with the mass at the highest point will be given by:
5)
where l is the lenght of the string.
Combining equations 4 and 5 and solving for ∅:
6)
Answer:
a
b
Explanation:
From the question we are told that
The current is
The length of one side of the square
The separation between the plate is
Generally electric flux is mathematically represented as
differentiating both sides with respect to t is
=>
Here is the permitivity of free space with value
=>
=>
Generally the displacement current between the plates in A
=>
