Hello, could anyone be generous enough to help me?

F = 0.08 N

Step-by-step explanation:

Force = 0.07 N when Distance = 6 m

Required

Find Force; when distance = 5.5m

The question says force is inversely proportional to square of distance;

Let F represent Force and D represent Distance;

Mathematically;

Fα1/D^2

Convert proportion to equation

F=k/D^2

Where k is the proportionality constant; This means that k is always constant

Make k the subject of formula

F*D^2=k/D^2*D^2

FD^2=k

When F = 0.07 and D = 6; the value of k is as follows

0.07*6^2=2.52=k

2.52=k

K=2.52

When d = 5.5;

Recall that k is always constant; so

To solve for F, we'll make use of

Substitute k=2.52 and d =5.5 ;

F=2.52/5.5^2=0.08N
