# What is the magnitude of the charge on a second object?

• rainyday4511
In summary, there is a problem involving two charged objects separated by 17 m. One object has a charge of 22 x10-6 C and the electrostatic force between them is 0.8 N. The question is asking for the magnitude of the charge on the second object, which can be solved using the equation F= 9x10^9 q1 q2 / D^2.

Yes.

F= 9x10 (with an exponent of 9) q1 q 2 divided by D2

Ok, does that equation apply to this problem? Which variables are unknowns in this situation?

## 1. What is the unit of measurement for charge?

The unit of measurement for charge is the Coulomb (C).

## 2. How is the magnitude of charge calculated?

The magnitude of charge can be calculated using Coulomb's Law, which states that the magnitude of the electrostatic force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

## 3. Can the magnitude of charge on an object be negative?

Yes, the magnitude of charge on an object can be negative. This indicates that the object has an excess of electrons, giving it a negative charge.

## 4. How does the magnitude of charge affect the strength of the electric field?

The magnitude of charge on an object directly affects the strength of the electric field around it. The greater the magnitude of charge, the stronger the electric field will be.

## 5. Is the magnitude of charge a fundamental property of matter?

Yes, the magnitude of charge is a fundamental property of matter. It is one of the four fundamental forces of nature and is a fundamental property of particles such as protons and electrons.
