PLEASE HELP DUE TODAY!! 1. A charged cup contains 69 electrons, Calculate the charge on the cup.
( charge of an electron is -1.6 x 10^-19 )

2. A charged particle has a charge of -9.2 x 10^-16 C. How many electrons are found in the
charged particle?

3. A charged ball has 27 protons. Calculate the charge on the ball.

4. There are 63 charged particles on the surface of a book. If the total charge on the book is
- 6.4 x10^-18 C, determine whether the charged particles on the surface of the book are
electrons or protons.

5. A charged particle contains 7000 protons. Calculate the total charge on the charged
particle.
