physics fields and charges
posted by charlie on .
2 charges, Q1 and Q2, equal magnitude, but different signs (not assigned) lie on a line, x axis, a known distance apart.
Segment pq lies centrally on the line, distance apart is known.
An electron is released at p from rest, and passes q at a given time later. The field at pq is constant.
My job is to find the size and sign of Q1 and Q2 on this info.
I believe i can calculate the electrical force on the electron, but where next? Thanks
