As you walk across a synthetic-fiber rug on a cold, dry winter day, you pick up an excess charge of (a) How many excess electrons did you pick up? (b) What is the charge on the rug as a result of your walking across it?

Answers:

A. e = -1.6 X10^-19.

B. +55 x 10^-6 C.

Explanation:

A.

Each electron has a charge of 1.6 x 10^-19 C.

So therefore,

N electrons would have a charge of = N * 1.6 x 10^-19 C

= 1.6 x 10^-19 N.

Ne = Q(charge)/e(charge)

e = -1.6 X10^-19

B.

Charge on the rug is +55 x 10^-6 C. Electrons on you were transferred from the rug. So the rug has the opposite charge from you.

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

its c its is a mixture of gases
