Yes gravity would be the force that is holding that object down

Well, it seems as though there would be no forces, because it's "at rest", but wouldn't gravity still be acting upon it?

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.

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
