Question

Если сила взаимодействия двух одинаковых электрических зарядов расположенных в вакууме на расстоянии 10 см равна 0,9 Ньютон то величина заряда составит... мкКл​

Answer 1

Ответ:1 мкКл

Объяснение: из закона Кулона F=k*|q1|*|q2| / r² имеем

q=√F*r²/k=r√F/k=0,1м*√0,9Н/9*10^9Н*м²/Кл²=0,1*10^-5 Кл=

= 1 мкКл

Answer 2

Calculating Electric Force between Charges

To calculate the electric force between two charges in a vacuum, we can use the formula:

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

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

Given that the electric force between two identical charges at a distance of 10 cm is 0.9 N, we can use this information to find the magnitude of the charge.

Calculating the Magnitude of the Charge

Using the formula for electric force and the given information, we can rearrange the formula to solve for the magnitude of the charge:

|q| = √(F * r^2 / k)

Substituting the given values: - F = 0.9 N - r = 10 cm = 0.1 m - k = 8.9875 * 10^9 N m^2/C^2

We can calculate the magnitude of the charge using the given values and the formula.

|q| = √(0.9 * (0.1)^2 / 8.9875 * 10^9) |q| = √(0.009 / 8.9875 * 10^9) |q| ≈ 3 * 10^-6 C

So, the magnitude of the charge will be approximately 3 μC (microcoulombs).
