Answer:
0.2s
Explanation:
Given parameters:
Speed = 25m/s
Distance = 5m
Unknown:
Time taken for Juan to get to his work = ?
Solution:
To solve this problem we use the relationship below:
Speed =
Time =
So;
Time =
= 0.2s
The electrostatic force between two charges is given by

where
ke is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the charges
In our problem,



Therefore the electrostatic force is
