1) 2 spheres of equal diameters have 15 micro coulomb charge and -10 micro coulomb charge respectively. if they are placed 5cm apart what will be the force of attraction between them?

2) a charge of .5 micro coulomb is placed in an electric field whose intensity is 4x10^5n/c. what is the electric static force acting on the charge?

thanks a log guys!

1) Well, it seems like these spheres are quite the electrifying couple! To calculate the force of attraction between them, we can use Coulomb's Law: F = (k * q1 * q2) / r^2. Here, k represents Coulomb's constant, q1 and q2 are the charges on the spheres, and r is the distance between them.

Let's plug in the values: q1 = 15 micro coulombs, q2 = -10 micro coulombs, and r = 5 cm (which is 0.05 meters, by the way). After doing the math, we find that the force of attraction will be determined with absolute shock and awe at 6 x 10^3 Newtons.

2) Ah, another electrifying scenario! To calculate the electric static force acting on the charge, we can use the formula F = q * E. Here, q represents the charge and E represents the electric field intensity.

Let's plug in the values: q = 0.5 micro coulombs (which is 0.5 x 10^-6 coulombs) and E = 4 x 10^5 Newtons per coulomb. After crunching the numbers, we find that the electric static force will grace us with its presence at a magnitude of 2 x 10^5 Newtons. Electrifying, isn't it?

Remember, these calculations are just for laughs!

1) To find the force of attraction between two charged spheres, we can use Coulomb's Law.

Coulomb's Law states that the force of attraction (F) between two charged objects is given by:
F = (k * |Q1 * Q2|) / r^2

where:
F is the force of attraction
k is the electrostatic constant (9 x 10^9 Nm^2/C^2)
Q1 and Q2 are the charges of the two spheres
r is the distance between the centers of the spheres

In this case, the charges of the two spheres are Q1 = 15 μC and Q2 = -10 μC. The distance between the spheres is r = 5 cm = 0.05 m.

Plugging these values into the equation, we have:
F = (9 x 10^9 Nm^2/C^2 * |15 μC * -10 μC|) / (0.05 m)^2

Simplifying:
F = (9 x 10^9 Nm^2/C^2 * 150 μC^2) / 0.0025 m^2
F = 6 x 10^12 N

Therefore, the force of attraction between the two spheres is 6 x 10^12 Newtons.

2) To find the electric static force acting on a charge in an electric field, we can use the formula:

F = q * E

where:
F is the electric force
q is the charge
E is the electric field intensity

In this case, the charge is q = 0.5 μC and the electric field intensity is E = 4 x 10^5 N/C.

Plugging these values into the equation, we have:
F = (0.5 μC) * (4 x 10^5 N/C)

Simplifying:
F = 2 x 10^5 μN

Therefore, the electric static force acting on the charge is 2 x 10^5 microNewtons.

1) To calculate the force of attraction between two charged spheres, we can use Coulomb's Law. Coulomb's Law states that the force between two charged objects is directly proportional to the product of their charges 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 between the spheres,
k is the electrostatic constant (approximately 9 × 10^9 N·m^2/C^2),
q1 and q2 are the charges of the spheres, and
r is the distance between the centers of the spheres.

In this case, one sphere has a charge of 15 micro coulombs (+15 μC) and the other has a charge of -10 micro coulombs (-10 μC). The distance between them is 5 cm or 0.05 m.

Plugging in the values into Coulomb's Law:

F = (9 × 10^9 N·m^2/C^2) * (15 μC * -10 μC) / (0.05 m)^2

Calculating this out will give you the force of attraction between the spheres.

2) To calculate the electric static force acting on a charge in an electric field, we can use the formula:

F = q * E

Where:
F is the force acting on the charge,
q is the charge, and
E is the electric field intensity.

In this case, the charge is 0.5 micro coulombs (0.5 μC), and the electric field intensity is 4 × 10^5 N/C.

Plugging in the values into the formula:

F = (0.5 μC) * (4 × 10^5 N/C)

Calculating this out will give you the electric static force acting on the charge.

Remember to convert units when necessary to ensure consistent calculations.
