1. A positron is an elementary particle identical to an electron except that its charge is
+ e. An electron and a positron can rotate about their center of mass as if they were a dumbbell connected by a massless rod.
What is the orbital frequency for an electron and a positron 1.70 nm apart? (Answer in Hz)
2. If someone could just define orbital frequency for me or point me in the direction of the right type of equation to use... I'm lost on this one and it's not in our textbook.
Possible relevant equation - electric field of a sphere of charge
E = Q/4[tex]\pi[/tex][tex]\epsilon\underline{}0[/tex]r[tex]\overline{}2[/tex]
that should read Q divided by (4 times pi times epsilon times r squared)
3. The fact that the positron has a +e charge but is identical tells me that the mass is still the same.
