An electron with a horizontal speed of 3.3 x 106m/s and no vertical component of velocity passes through two horizontal parallel plates, as shown in the diagram below. The magnitude of the electric field between the plates is 180 N/C. The plates are 7.5cm long.
Calculate the vertical component of the electron after it leaves the plates.
Calculate the final velocity of the electron.
The coefficent of static friction between the ladder and the ground is 0.500.
An unstable particle is at rest and suddenly breaks up into two fragments. No external forces act on the particle or its fragments. One of the fragments has a velocity of +0.800c and a mass of 1.87 10-27 kg, while the other has a mass of 4.31 10-27 k..

Radium decomposes radioactively to form radon (atomic number 86, which is also the number of protons in the nucleus) by emitting an alpha-particle from its nucleus, What is the acceleration of the alpha-particle at this distance
A pressure as low as P = 8 ? 10-11 Pa has been obtained. Suppose a chamber contains helium at this pressure and at room temperature, Estimate the mean free path
Concept to find certain type of electronic devices & circuits.
At takeoff a commercial jet has a 55.0 m/s speed. Its tires have a diameter of 0.550 m.
A moving particle encounters an external electric field that decreases its kinetic energy from 9520 eV to 7060 eV as the particle moves from position A to position B. The electric potential at A is -55.0 V, and the electric potential at B is +27.0..
