1. charged particles can affect and be affected by
other charged particles through the electric fields they produce.
other particles, but only if they have the opposite charge.
other particles, but only if they have the same charge.
fields of attractive, but not repulsive, force.
2.what is the term for the force experienced by a charged particle in an electromagnetic field?
the oersted force
the tesla force
the gauss force
the lorentz force
3.which of the following fields is a "vector field"?
electric only
magnetic only
electric and magnetic
neither electric nor magnetic
4.which of the following formulas can be used to find the magnitude of the force on a charge moving at an angle θ through a magnetic field?
f = qeθ
f = qvbsinθ
f = macosθ
f = qvbcosθ
5.how do stationary charged particles interact at a distance with their surroundings?
by emitting protons into the surroundings
by creating magnetic force fields
by breaking up into smaller charges
by way of their electric fields
6.an electric field always surrounds
uncharged particles
negatively and positively charged particles
only positively charged particles
only negatively charged particles a
7.when hans christian oersted discovered the connection between electricity and magnetism in 1820, he initially assumed that the magnetic field around a wire radiated evenly along all sides, like light or heat. what is the actual shape of the magnetic field of a wire?
radially oriented but expanding and contracting in strength
rod-shaped, contained entirely within the wire
a spring-like spiral with the wire along its axis
concentric circles centered on the wire
8.moving a magnet creates electric forces that can
create significant gravitational potential energy
induce electric current in a wire
cancel out the magnetic forces
move uncharged particles
9.how are an electromagnet's magnetic field lines directed?
parallel to the electric field lines
from the magnet's south pole to its north pole
from the magnet's north pole to its south pole
in straight lines radially from the north pole
10.if a charged particle is moving parallel to a magnetic field, it experiences
the maximum force possible
half of the maximum force possible
a force with a direction parallel to the magnetic field
no force

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
