A. |
A temporary positive charge |
|
When
the positively charged rod is brought close to the electroscope, electrons
flow into the electroscope from the ground because of the attraction of
unlike charges.
If the positively charged rod is removed when
the wire is still in place, the electrons will leave after the rod is
removed.
However, since the connection is broken while
the rod is still close; the electrons cannot leave the electroscope.
This leaves the electroscope with a permanent negative charge.
The Correct Answer is D. |
