kati45 [8]

Answer:

0.12959085 J

Explanation:

k = Coulomb constant = 8.99\times 10^{9}\ Nm^2/C^2

q = Charge = 1.55 μC

d = Distance between charge = 0.5 m

Electric potential energy is given by

U=k\dfrac{q^2}{d}

In this system with three charges which are equidistant from each other

U=k\dfrac{q^2}{d}+k\dfrac{q^2}{d}+k\dfrac{q^2}{d}

\\\Rightarrow U=k\dfrac{3q^2}{d}\\\Rightarrow U=8.99\times 10^9\times \dfrac{3\times (1.55\times 10^{-6})^2}{0.5}\\\Rightarrow U=0.12959085\ J

The potential energy of the system is 0.12959085 J

Ket [755]

The Earth's atmosphere is generally understood as air. It is the coating of gases controlled by Earth's gravity.'High pressure to low pressure is the statement that describes the movement of air in general.

<h3>What is air?</h3>

The  Earth's atmosphere generally understood as air, is the coating of gases controlled by Earth's gravity that covers the planet and begins its planetary atmosphere.

It is very important to survive on the earth. It is the basic need of the human body. Many plant reactions include the composition of air.

Air always flows from high pressure to low pressure.

Hence High pressure to low pressure is the statement that describes the movement of air in general.

To learn more about the air refers to the link;
