HW to be turned in next class

Electrostatics homework – to be turned in Thursday

1.  Define charge.

2.  Explain why a charged balloon will stick to a (neutral) wall.

3.  What is the charge (in coulombs) of a proton?

4.  How many protons does it take to make 1 coulomb of charge?

5.  In any atom, which particle(s) are fundamental and which are composite (made of smaller particles)?

6.  You have two clusters of charge:  10 C and 20 C, separated by 1-m of distance.
a.  Use Coulomb’s law to calculate the force that exists between the charges.
b.  Is this force attractive or repulsive?
c.  If you were to double the distance between the charges, what exactly would happen to the amount of force between the charges?

7.  Carbon is element number 6.
a.  What does the 6 represent?
b.  What do you suppose is the difference between Carbon-12 and Carbon-14?
