For the equation part:
The equation is f = Gm1m2/d^2
I know that G = (6.67×10−11Nm^2/kg^2)
f = 8.5N
d^2 = 7.5 x 10^6 m
The problem I am having is that I do not know how to rearrange the equation and solve for m1 or m2.And I understand part b now, thank you!
For question A, I know that I am supposed to input the numbers given into the Universal Gravitation Equation, but I do not know how to solve for it beyond that.
For question B, I know that the astronauts weight depends on the mass and gravity of the new planet but I do not know how to prove it...
