#CARRYONLEARNING
Answer:
2.30 × 10⁻⁸ N if the two electrons are in a vacuum.
Explanation:
The Coulomb's Law gives the size of the electrostatic force
between two charged objects:
,
where
is coulomb's constant.
in vacuum.
and
are the signed charge of the objects.
is the distance between the two objects.
For the two electrons:
.
.
.
The sign of
is negative. In other words, the two electrons repel each other since the signs of their charges are the same.
Savanna regions developed during the Triassic period. is true
