The charge Q is 512 c.
Step-by-step explanation:
Step 1:
The equation is
, where q and Q are the charges, R is the distance between the charges, and F is the force between the charges.
From the question, we have;
F = 40 Newton, R = 16 m and q = 20 C.
We need to calculate Q.
Step 2:
By substituting the values of F, R, and q in the equation, we get
.
We cross multiply to solve Q.

So Q = 512 C.
It’s C. If you place the numbers from least to greatest, 126 (C) will be in the middle, or center.
We know that
[total trail]=(3/4)*2------> 6/4---------> (3/2) miles
<span>[fraction of a mile that katenka did]=(2/3)*(3/2)------> 1 mile
the answer is 1 mile</span>
