Find the force of attraction between two equal but opposite charges of 2*10^-6 if the distance between them is 25cm
To find the force of attraction between two charges, we can use Coulomb's Law. Coulomb's Law states that the force of attraction or repulsion between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them.
The formula for Coulomb's Law is:
F = (k * q1 * q2) / r^2
Where:
- F is the force of attraction or repulsion between the charges,
- k is the electrostatic constant (k = 8.99 * 10^9 Nm^2/C^2),
- q1 and q2 are the magnitudes of the charges, and
- r is the distance between the charges.
In this case, we have two equal but opposite charges of magnitude 2 * 10^-6, and the distance between them is 25 cm, which is 0.25 meters.
Plugging these values into the formula, we get:
F = (8.99 * 10^9 Nm^2/C^2) * (2 * 10^-6 C) * (2 * 10^-6 C) / (0.25 m)^2
Calculating this expression will give us the force of attraction between the charges.
