1.a) What type of motion does an electron initially moving at 1.5x10^6m/s parallel to the 2 V equipotential line in an ideal capacitor (as shown above) show? Explain, referring to the acceleration and similarity to a motion in a gravitational force. b) When the electron reaches the 7 V equipotential line, what angle theta does its velocity vector make with the equipotential line? e=1.602x10^-19 C, me=9.11x10^-31 kg. 2.a) At what initial speed would one have to send a positron (a...
1. (A) Find the de Broglie wavelength (in nm) associated with an electron that is moving with a velocity of 2310 km/s. The electron rest mass is 9.11 x 10-31 kg. Note, electrons having this speed would need to be treated as waves in atoms because the wavelength is on the order of the size of atoms. (B) A baseball weighs 220 g. Top speed for a professional pitcher is about 100 mph when he throws a fast ball. Find...
What is the escape speed for an electron initially at rest on the surface of a sphere with a radius of 1.2 cm and a uniformly distributed charge of 1.8 * 10-15 C? That is what initial speed must the electron have in order to reach an infinite distance from the sphere and have zero kinetic energy when it gets there? The charge of an electron is 1.602 x 10-19 C and its mass is 9.109 10-31 kg.

Question 1 2 pts In the figure below, a charged particle (either an electron or a proton) is moving rightward between two parallel charged plates separated by distance d-1.25mm. The plate potentials are V=-65V and V2=-40V. The particle is slowing from an initial speed of 90.0 km/s at the left plate. What is its speed just as it reaches plate 2? Express the speed in units of km/s i.e. 10 m/s, and up to one decimal place.
