An electron in an oscilloscope tube is traveling horizontally with a speed of 4.4×106m/s . It passes through a 2.1cm long region with an electric field pointing upward with a magnitude of 1500N/C. what is the magnitude of the electron’s velocity when it e...

Two protons in a nucleus are separated by 8.0×10−15m . What's the potential energy of the pair?

A proton is held at a fixed position. An electron is placed 0.85m away and released. Find the electron's speed when it's 9.0mm from the proton.
