Answer:
The value of new coulomb force is 1.43 N.
Explanation:
Given;
Coulomb's force in vacuum (air), 
= 10 N
dielectric constant, K = 7
The Coulomb's force between two charges separated by a distance r in a vacuum is given as;
The Coulomb's force between two charges separated by a distance r in a medium with dielectric constant is given as
Take the ratio of the two forces;
Therefore, the value of new coulomb force is 1.43 N.

Explanation:
THIS DOES NOT NEED TO BE EXPLAINED IT'S EZZZ
The power exerted by the cyclist is determined as 50 W.
<h3>
Average power exerted by the cyclist</h3>
The power exerted by the cyclist is calculated as follows;
P = FV
where;
- F is the applied force
- V is velocity
P = 20 x 2.5
P = 50 W
Thus, the power exerted by the cyclist is determined as 50 W.
