A point charge of 5.0 x 10^-7 C moves to the right at 2.6 x 10^5
m/s in a magnetic field that is directed into the screen and
has a field strength of 1.8 x 10^-2 T.
What is the magnitude of the magnetic force acting on the
charge?
OON
2.3 x 10-3N
23 N
2.3 x 1011 N.

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earth’s magnetic field, which is 0.50 g. is this value cause for worry?

Does current flow through or across a resistor?
