Question

kisse ko pata hai toh batade because this quyis very hard​

Answer 1

Your answer bro:

F = $\frac{GMm}{r^2}$

G = 6.67 x 10⁻¹¹

Now, M = 5.5

         m = 2.9

F = 2.7 x 10⁻¹²

Substituting all the values, you will get:

2.7 x 10⁻¹² = $\frac{5.5\times2.9\times6.67\times10^-^1^1}{r^2}$

r² = $\frac{5.5\times2.9\times6.67\times10^-^1^1}{2.7\times10^-^1^2}$

r² = 394.02

r =  $\sqrt{394.02}$ = 19.85 = 19.9 approx
