not necessary

a barometer? interesting.

BINGO!

I'm single (and looking), but I do know the answer.

It'll be the best physics textbook you've ever read!!!!!! If you're a faculty member, just ask your Wiley rep for a copy.

...i'd like to listen in on THAT call...

I can practically guarantee that no doctoral candidate would get this one.

Here are a dozen of my thoughts... after thinking for a long long while...

 

1. Use a charged calibrated electroscope ?

2. Use a calibrated electrometer ?

3. Set up apparatus that measures microforces between the scotch tape

and a charged object of the same size that has a known charge ?

4. Offer to give a knowledgeable professor a barometer if he tells me

how to measure the charge on a piece of scotch charged tape. ?

5. Give the problem to students in one of my physics classes

for homework or as a question on their final examination. ?

6. Contact Joe Haefner's wife and find out whether or not Joe

knows the answer himself?

7. Spend $70 for a book that Joe Haefner recommends that might

or might not have the answer?

8. Contact the manufacturers of scotch tape and ask their customer

service girl ?.

9. Ask one of my friends who gives oral exams to physics doctoral

candidates to include this question on all of his future interviews?

10. Apply to the NSF for a grant to research the answer to my question?

11. Pose my question to members of this Phys-L listserve and

hope for a correct response within the next year or two?

12.Do a thorough computer web search using the GOOGLE or several other search engines and hire someone to translate hits in several of the foreign language publications?.
