Suppose an electron is in the picture tube of a television is accelerated from rest through a potential difference of of +5000 volts, what is the change in the electrons potential energy? and what is it final velocity?
Determine the potential at a point 0.5 meters from a +20μC charge? and the potential 0.5 meters from a -20μC charge?
How much work (J) must be done to bring a charge q= +3μC from a great distance (like ∞ ) to a point 0.5 m from a charge Q= +20μC?
Looks a little crazy, but is totally safe. Just like the birds on the wire.
