Y = n
y = x^2 + n
n > 0
since there are 2 equations equal to y, set them equal to each other and solve.
n = x^2 + n
Subtract n from both sides.
0 = x*2
Take the square root of both sides.
x = 0
Hi there!
F =
![\dfrac {km}{r^2}](https://tex.z-dn.net/?f=%5Cdfrac%20%7Bkm%7D%7Br%5E2%7D)
To solve for ' r '
Follow these steps :-
• Multiply r² both sides -
F × r² =
![\dfrac {km}{r^2}](https://tex.z-dn.net/?f=%5Cdfrac%20%7Bkm%7D%7Br%5E2%7D)
× r²
F × r² = km
• Divide F from both sides -
r² =
![\dfrac {km}{F}](https://tex.z-dn.net/?f=%5Cdfrac%20%7Bkm%7D%7BF%7D)
r =
![\sqrt{ km/F }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20km%2FF%20%7D%20)
Hence,
Option D. r =
![\sqrt{ km/F }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20km%2FF%20%7D%20)
is Correct
