The electrostatic force between two charges Q1 and q is given by
where
ke is the Coulomb's constant
Q1 is the first charge
q is the second charge
r is the distance between the two charges
Re-arranging the formula, we have
and since we know the value of the force F, of the charge Q1 and the distance r between the two charges, we can calculate the value of q:
And since the force is attractive, the two charges must have opposite sign, so the charge q must have negative sign.

Answer: Yes
Explanation:
Velocity is defined as the distance traveled
in a specific time
:
If you are traveling at a distance
, then the time it will take you to be at work is:
This means you will make it on time, because this time is less than 0.25 h.
