I CANNOT DO THIS, PLEASE HELP! :D

F = k/d^2

Step-by-step explanation:

We can see from the question that the force of attraction F is proportional to the inverse of the square of the distance separating the bodies, d.

So we have;

F α 1/d^2

So,  introducing a constant of proportionality k,

F = k/d^2

Hence the formula connecting F and d is; F = k/d^2

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
