Где k = 9*10^9 (постоянная)
q1 и q2 = 10^-6
r=6см=0.06м

Answer 2

Calculating the Electric Force Between Two Point Charges

To calculate the electric force between two point charges, we can use Coulomb's law, which states that the magnitude of 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. The formula for the electric force between two point charges is given by:

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

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

Applying the Given Values

In this case, we have two point charges with the same magnitude of 4 nC (nanocoulombs) and a certain distance between them. Let's denote the distance between the charges as d.

Given: - Magnitude of each charge, q1 = q2 = 4 nC - Distance between the charges, d = ?

We can use the given information to calculate the electric force between the charges.

Calculating the Electric Force

Using the formula F = k * |q1 * q2| / r^2, and substituting the given values, we get:

F = (8.9875 x 10^9 N m^2/C^2) * |4 x 10^-9 C * 4 x 10^-9 C| / d^2

We can calculate the electric force once we have the value of d.

Conclusion

To calculate the electric force between the two point charges, we need the specific value of the distance between them. Once the distance is known, we can use the formula to determine the magnitude of the force.
