Answer:
The system's energy amounts to 15 J.
Explanation:
Given that,
Energy E = 2.5 J
Amplitude = 10 cm
The spring constant needs to be computed.
Using the formula for the mechanical energy of the system,
Substituting the values into the formula:
If the block is swapped out for one with double the original mass,
Amplitude = 6 cm
We need to find the energy
Using the mechanical energy formula,
Substituting into the formula:
Thus, the system’s energy is 15 J.
Answer:
The correct choice is C: points 1, 4, and 5 are equal, followed by 2 and 3 being equal.
Explanation:
Here’s the breakdown:
The electric field from the positive sheets E₁ = б/2E₀
E₂ is from the negative sheet = -б/2E₀
At points 1, 4, and 5, the electric fields created by the sheets oppose each other.
At point 1, the total field is calculated as -E₁ + E₂ = 0.
Similarly, at point A, the total field results in -E₁ - E₂ = 0.
However, at any point in between the plates, the electric field is directed consistently in one way.
At points 2 and 3, the field is directed to the right.
Thus, we have:
E net = E₁ + E₂
= б/2E₀ + -б/2E₀
=б/E₀
