Answer:
The correct answer to the following question will be "41.87 m".
Explanation:
The given values are:
The speed of trooper =
The velocity of red car =
Now,
A red car goes as far as possible until the speed or velocity of the troops is the same as that of of the red car at
(∵
)
then,
The distance covered by trooper,
The distance covered by red car,
=
=
Maximum distance =
=
The electrostatic force between two charges q1 and q2 is given by
where
is the Coulomb's constant
is the distance between the two charges.
In our problem, the two charges are two electrons, so their charges are equal and equal to
By substituting these values, we find the intensity of the force between the two electrons:
This is the magnitude of the force each electron exerts to the other one. The direction is given by the sign of the charges: since the two electrons have same charge, they repel each other, so the force exerted by electron 1 is toward electron 2 and viceversa.
