In a thundercloud there may be electric charges of 45.0 C near the top of the cloud and -45.0 C near the bottom of the cloud. These charges are separated by 2.30 km. What is the electric force on the top charge?

Respuesta :

Answer:

The electric force on the top charge is [tex]F=3.44\times 10^6\ N[/tex].

Explanation:

Given that,

Electric charges in a thundercloud, [tex]q_1=q_2=45\ C[/tex]

The distance between charges, d = 2.3 km = 2300 m

Let F is the electric force on the top charge. The electric force is given by the formula as :

[tex]F=\dfrac{kq^2}{d^2}[/tex]

[tex]F=\dfrac{9\times 10^9\times (45)^2}{(2300)^2}[/tex]

[tex]F=3445179.58\ N[/tex]

or

[tex]F=3.44\times 10^6\ N[/tex]

So, the electric force on the top charge is [tex]F=3.44\times 10^6\ N[/tex]. Hence, this is the required solution.
