Homework Statement
As an electron moved through a region of space, its speed changed from an initial velocity of vi=8114.3 km/s to the final velocity vf=2233.7 km/s. The electric force was the only force acting on the electron.
Across what potential difference did the electron travel...
Two charges, q1=-9.4 μC and q2=1.2 nC with masses m1=13.4 gram and m2=2.7 gram were
located 8.5 cm from each other. Charge q1 is held in place.
We wish to push the 2nd charge q2 as far from the 1st charge as possible.
With what initial velocity should charge q2 be pushed to send it all the...
