Which two pieces of data indicate that Uranus resides in the outer region of the solar system

LuckyWell [14K]

Answer:

Our solar system has total eight planets out of which four are inner planets and four are outer planets. The four outer planets are Jupiter, Saturn, Uranus and Neptune. The common characteristics of outer planets is that they are gaseous planets. They are larger on size than the inner rocky planets and are faraway from Sun. They have larger period of revolution around the Sun.

Uranus is a gaseous planet and lies far from Sun and hence has large period of revolution. It takes 84 Earth years to revolve around Sun. This data indicates that Uranus resides in the outer region of the Solar System.

Two point charges are on the y axis. A 4.50-σC charge is located at y=1.25 cm , and a -2.24-σC charge is located at y=-1.80 cm.

kvasek [131]

Two point charges are on the y axis. A 4.50-σC charge ( $q_1$ ) is located at y=1.25 cm ( $r_1$ ) , and a -2.24-σC charge ( $q_2$ ) is located at y=-1.80 cm ( $r_2$ ).

The total electric potential at the origin is $2.12\times10^6V$ .

How to calculate the total electric potential at the origin?

The total electric potential at some point due to several point charges is represented by:

$V=k_e \sum _i \frac{q_i}{r_i}$

Here,

$k _e= 8.988 \times 10^9 N \cdot m^2/C^2$ (Columbic constant)

The total electric potential at point $O$ is the sum of the potentials due to $q_1$ and $q_2$ will be:

$V_O=k_e(\frac{q_1}{r_1} +\frac{q_2}{r_2} )$

Substituting the values, we get:

$V_O=8.988\times10^9(\frac{4.5 \times 10^{-6}}{0.0125} +\frac{-2.24\times10^{-6}}{0.018} )=2.12\times10^6V$

Hence, the total electric potential at the origin is $2.12\times10^6V$ .4
