What is the orbital period in years of a planet with a semi major axis of 35 au
1 answer:
Answer:
Orbital period of the planet will be 207.06 year
Explanation:
We have given the planet have the semi major axis as 35 au
We have to find the orbital period of the planet
From Keplar's third law there is relation between the orbital period and semi major axis which is t
So
So orbital period of the planet will be 207.06 year

Answer:
E_total = 5.8 10⁴ N /C
Explanation:
In this problem they ask to find the electric field at two points, the electric field is a vector magnitude, so we can find the field for each charged shoah and add them vectorally at the point of interest.
To find the electric field of a charged conductive sheet, we can use the Gauss law,
Ф = E. d S = / ε₀
Let us use as a Gaussian surface a small cylinder, with the base parallel to the sheet, the electric field between the sheet and the normal one next to the cylinder has 90º, so its scalar product is zero, the electric field between the sheet and the base has An Angle of 0º, therefore the scalar product is reduced to the algebraic product.
Let's look for the electric field for plate 1
The total flow is the same for each face, as there are two sides of the cylinder
2E A = q_{int} /ε₀
For the internal load we use the concept of surface density
σ = q_{int1} / A
q_{int1} = σ₁ A
Let's replace
2E A = σ₁ A /ε₀
E₁ = σ₁ / 2ε₀
For the other plate we have a field with a similar expression, but of negative sign
E₂ = -σ₂ / 2ε₀
The total field is,
E_total = σ₁ / 2ε₀ + σ₂ / 2ε₀
E_total = (σ₁ + σ₂) / 2ε₀
Let us apply this expression to our case, when placing a sheet without electric charge, a charge is induced for each sheet, the plate 1 that has a positive charge the electric field is protruding to the right and the plate 2 that has a negative charge creates a incoming field, to the right, as the two fields have the same address add
The conductive sheet in the middle pate undergoes an induced load that is created by the other two plates, but because the conductive plate the charges are mobile and are replaced.
E_total = (0.51 +0.52) 10⁻⁶ / 2 8.85 10⁻¹²
E_total = 5.8 10⁴ N /C
Note that the field is independent of the distance between the plates
