Electrostatics - Compute the electric charge

In summary, three point charges q1, q2, and q3 are arranged in a triangle and have different amounts of extra electrons. The electric charge of each charge is calculated by using the formula V=u/q, but this does not work and the person is unsure of how to proceed. They are then reminded to look up the charge per electron and thank their mentor for the hint.

Homework Statement


three point charges q1,q2&q3 are place at the vertices of triangle as shown in the diagram charge q1 has been given 4.5 X 10^13 extra electrons, charge q2 given 9.0 X10^13 extra electrons and q3 has had 9.0 X 10^13 electrons taken from it. Calculate the electric charge of q1,q2,&q3?


Homework Equations


no,sorry..

3. The Attempt at a Solution [
1stly i use the formula V=u/q to find the charge but it doesn't work,so I'm stuck with it!

ohh..ya,i wasn't realize about it..thanks for the hint,mentor..thanks alot..=>
 

1. What is electrostatics and how does it relate to electric charge?

Electrostatics is the branch of physics that deals with the study of electric charges and their interactions. Electric charge is a fundamental property of matter, and electrostatics explains how it is created and how it behaves in different situations.

2. How is electric charge measured?

Electric charge is measured in units of coulombs (C). It is usually measured using an instrument called an electroscope, which can detect the presence and magnitude of electric charge.

3. What is the difference between positive and negative electric charges?

Positive electric charges are created by protons, which have a positive charge. Negative electric charges are created by electrons, which have a negative charge. Opposite charges attract each other, while like charges repel each other.

4. How do you compute the electric charge of an object?

The electric charge of an object can be computed by adding up the individual charges of all the particles that make up the object. For example, the charge of an atom is equal to the sum of the charges of its protons and electrons.

5. Can electric charges be created or destroyed?

No, according to the law of conservation of charge, electric charges cannot be created or destroyed. They can only be transferred from one object to another through the movement of electrons.
