Question

заряды 50 нкл и 20нкл находятся на расстоянии 3 см друг от друга в воздухе . определение силу их взаимодействия.

Answer 1

Объяснение:

Дано

q1=50 нКл = 50×10`⁹ нКл

q2=20 нКл = 20×10`⁹ нКл

r=3см= 0,03 м

k=9×10⁹Н×м²/Кл²

Найти

F=?

Решение

F= k× q1×q2/r²

F= 9×10⁹×(50×10`⁹×20×10`⁹)/0,03² = 10`² Н= 0,01 Н

Ответ: 0,01 Н или 10`² Н

Answer 2

Calculating the Force of Interaction between Charges

To calculate the force of interaction between the two charges, we can use Coulomb's law, which states that the force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between their centers. Mathematically, Coulomb's law is expressed as:

F = k * |q1 * q2| / r^2

Where: - F is the magnitude of the force between the charges, - k is Coulomb's constant (approximately 8.9875 x 10^9 N m^2/C^2), - q1 and q2 are the magnitudes of the charges, and - r is the distance between the charges.

Applying Coulomb's Law to the Given Scenario

In this scenario, we have two charges: 50 nC and 20 nC, located 3 cm apart in air. We can calculate the force of interaction between them using Coulomb's law.

First, we need to convert the distance from centimeters to meters: - 3 cm = 0.03 m

Now, we can use the given charges and distance to calculate the force of interaction. Plugging the values into Coulomb's law:

F = (8.9875 x 10^9 N m^2/C^2) * |50 x 10^-9 C * 20 x 10^-9 C| / (0.03 m)^2

Calculating the force using the given values: - F ≈ 2.997 x 10^-3 N

Therefore, the force of interaction between the 50 nC and 20 nC charges, located 3 cm apart in air, is approximately 2.997 x 10^-3 N.
