2 spheres of equal diameters have a positive 15 micro column and negative 10 micro column charge if they are place 5 cm apart what would be the force of attraction between them.

To calculate the force of attraction, we can use Coulomb's Law, which states that the force of attraction between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them.

Given:
Charge on Sphere 1 (q1) = +15 μC = 15 × 10^-6 C
Charge on Sphere 2 (q2) = -10 μC = -10 × 10^-6 C
Distance between the spheres (r) = 5 cm = 5 × 10^-2 m

Using Coulomb's Law, the formula for the force of attraction (F) is:

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

where
k is the electrostatic constant and is equal to 8.99 × 10^9 N m^2/C^2.

Calculating the force of attraction:

F = (8.99 × 10^9 N m^2/C^2) * |(15 × 10^-6 C) * (-10 × 10^-6 C)| / (5 × 10^-2 m)^2

F = (8.99 × 10^9 N m^2/C^2) * (15 × 10^-6 C) * (10 × 10^-6 C) / (5 × 10^-2 m)^2

F = (8.99 × 10^9 N m^2/C^2) * (150 × 10^-12 C^2) / (5 × 10^-2 m)^2

F = (8.99 × 10^9 N m^2/C^2) * (150 × 10^-12 C^2) / (25 × 10^-4 m^2)

F = (8.99 × 10^9 N m^2/C^2) * (150 × 10^-12 C^2) / 25 × 10^-4 m^2

F ≈ 53.94 × 10^-5 N

Therefore, the force of attraction between the two spheres is approximately 53.94 × 10^-5 N.

To find the force of attraction between two charged spheres, we can use Coulomb's Law, which states that the force of attraction (or repulsion) between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Coulomb's Law formula is given by:

F = (k * |q1 * q2|) / d^2

Where:
F is the force of attraction (or repulsion) between the charges,
k is Coulomb's constant (approximately equal to 9 * 10^9 Nm^2/C^2),
|q1| and |q2| are the magnitudes of the charges on the spheres,
and d is the distance between the centers of the spheres.

In this case, the magnitudes of the charges on the spheres are 15 microcoloumbs (15 μC) and 10 microcoloumbs (10 μC), respectively. The distance between the spheres is 5 cm, which is 0.05 meters.

Let's substitute the given values into the formula to calculate the force of attraction:

F = (k * |q1 * q2|) / d^2
F = (9 * 10^9 Nm^2/C^2) * (15 * 10^-6 C) * (10 * 10^-6 C) / (0.05 m)^2

Calculating the above expression will give us the force of attraction between the charged spheres.

I think you'd better get out of physics. If you can't pay enough attention to distinguish "column" from "Coulomb" the details of solving problems is way past your pay grade.
