Answer:
No
Explanation:
Electric potential is the work done to bring a unit of charge (1 C) from infinity to a point inside an electric field.
Electric potential energy of a charge q is the energy required to keep it in an electric potential V. Electric potential energy is given by,
U = qV
Hence even if the two charges are on an equipotential surface (surface where the potential is the same at all points), the potenial energy will be different if the magnitude or nature of the charges are different.
Answer:
<span>5010J</span>
Explanation:
Work is force times distance, or
<span>W=F⋅d</span>.
Substitute in values from the question to get
<span>W=8.35⋅<span>102</span>N⋅6m=50.1⋅<span>102</span>Nm=5010<span>J</span></span>
One of the most surprising things about a superconductor is that
it has NO electrical resistance. The resistance doesn't just become
very very very small. It becomes literally completely zero. (This is
a big part of the reason why it's called a "super-conductor".)
If you start an electric current flowing in a superconductor, you can
connect the ends of it together, and the current keeps going around
and around the loop and never dies out !
Answer:
From Newton's 2nd Law, we have 
. Substituting given values, we have:
