An electron beam in an oscilloscope is deflected by the electric field produced by oppositely charged metal plates. If the electric field between the plates is 2.75 105 N/C directed downward, what is the force on each electron when it passes between the plates?

F = qE. You're given the E field. Look up the fundamental charge in the front cover of your book.

From the definition of the electric field we have:
F = −q0 * E, where q0 is the elementary charge 1.6×10−19 coulomb, so
F = −4.4x10−14 N (minus sign tells us that the force acts opposite to the field, upward).

properly nuclear tension is an somewhat short ranged tension, that's it applies to an somewhat short distance. It basically acts between nucleons(protons and neutrons). it extremely is of the order of 10^-15 and electrons are located exterior the nucleus and lots remote from it. So, each and every time gentle falls on them of acceptable frequency, they soak up it and are waiting to visit bigger stages.
