A 3.0-mm-diameter copper ball is charged to 90 nC. What fraction of its electrons have been removed? The density of copper is 8900 kg/m3.
The surface charge density (eta) h of an infinite charged plane is -2.0 x 10-6 C/m2. A proton is shot straight away from the plane at 2.0 x 106 m/s.
Make a sketch of the situation.
How far does the proton travel before reaching its turning point?
the nucleus of a 125Xe atom (an isotope of the element xenon with mass 125 u) is 6.0 fm in diameter. It has 54 protons and charge q=+54e (1 fm = 1 femtometer = 1×10−15m.) Hint: Treat the spherical nucleus as a point charge.
What is the proton's acceleration?
