Answer:

1. $Q = 5.56 * 10^(-3) C$

2. $Q = 2.97 * 10^(-12) C$

Explanation:

1. Electrostatic force is given as:

$F = (kqQ)/(r^2)$

where k = Coulombs constant

q = charge of first charge

Q = charge of the second charge

r = distance between them

From the question:

F = 100 N

q = $2 * 10^(-10) C$

r = 0.01 m

We need to find Q.

From the formula of force, we have that Q is:

$Q = (Fr^2)/(kq)$

$Q = (100 * 0.01^2)/(8.99 * 10^9 *2 * 10^(-10)) \n\n\nQ = (0.01)/(1.798)\n \n\nQ = 0.00556 C = 5.56 * 10^(-3) C$

This is the charge, Q, of the second charge.

2. From the question:

F = 2 N

q = $3 * 10^(-6) C$

r = $2 *10^(-4) m$

We need to find Q.

Using the same formula for Q as in 1. above, we have that:

$Q = (2 * (2 *10^(-4))^2)/(8.99 * 10^9 *3 * 10^(-6)) \n\n\nQ = (8 * 10^(-8))/(26970)\n \n\nQ = 2.97 * 10^(-12) C$

This is the charge, Q, of the second charge.

Answer:

(1) $4.4835*10^(17)C$

(2) $2.9748*10^(-12)C$

Explanation:

Force Between two charges is give by.

$F=k(Q_1 *Q_2)/(r^2)$ , here k is called coulomb constant and has value = $8.967*10^9Nm^2/C$ .

(1) case, F =100N, r = 0.1m and $Q_1$ = $2*10^(-10)C$ substituting these values in above equation and solving for unknown gives us.

$Q_2 = 4.4835*10^(17)C$ .

(2) Case, F = 2N, r = $2*10^(-4)m$ and $Q_1=3*10^(-6)C$ .

again by substituting these in above equation and solving for unknown gives us.

$Q_2=2.9748*10^(-12)C.$

An element becomes a positively charged ion when it losses electron.

What is electric charge?

Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge. You can have a positive ornegative electric charge (commonly carried by protons and electrons respectively). Unlike charges attract one another while like charges repel one another. Neutral refers to an object that carries no net charge.

Electric charge is a conserved attribute, meaning that the net charge—that is, the sum of the positive and negative charges in an isolated system—cannot change. Subatomic particles carry an electric charge. In the nuclei of atoms, protons have positive charge and electrons carry negative charge in normal matter.

So, an element becomes a positively charged ion when it loses negative charge, that is, electron.

Identify two ways of changing the strength of an electric force

Answers

When you talk about "the strength of an electric force" in middle school, I'm pretty sure you're talking about the force between two electrostatic charges that either pulls them together or pushes them apart.

The strength of that force depends on

-- the product of the amounts of charges on the two charged objects

-- the distance between the centers of their charges.
