2.charged comb contains 1000 electrons. Calculate the charge on the comb.

( charge on an electron = -1.6 x 10^-19 C )

3. A charged particle has a charge of - 4.8 x 10^-16 C. How many electrons are found in

the charged particle? ( charge on an electron = -1.6 x 10^-19 C )

4. A negatively charged balloon has a total charge of 5.0 x 10^21 electrons. Calculate the

total charge on the balloon. ( 6.25 x 10^18 electrons carry 1C of charge )
