Explanation:
a) From Coulombs law,
F = (kq1q2)/r²...............1
F = 10 N
r = 10m
k = 9 × 10^9 m/F
q1 = q2
from equation 1, make q the subject
q = (Fr²)/2k
q = (10×10²)/(2×9×10^9)
q = 1000/1.8×10^10
q = 5.556×10^-8 C
b) K = k/ko
k = Kko = 10times permittivity of free-space

The mileage of the car how fast it is going
Answer:
C) either depending on her running direction
Explanation:
The following information is given in the question
katelyn runs at 8 m/s
her speed relative to the floor is 3 m/s
Based on the above information
Now her speed relative with respect to an observe for the rest on the ground would be based on her running direction that means in which direction she is running
Therefore the option c is correct
