Which of the following would be a proper setup for this problem: A 60 kg person is standing on earth's surface (radius = 6.4x10⁶ m). The mass of earth is 6x10²⁴ kg.

• $\frac{\left(6.67x10^{-11}\right)\left(60\right)\left(6x10^{24}\right)}{\left(6.4x10^6\right)^2}$

• $\frac{\left(6.67x10^{-11}\right)\left(60\right)\left(6.4x10^6\right)}{\left(6x10^{24}\right)^2}$

• $\frac{\left(6.67x10^{-11}\right)\left(60\right)\left(6x10^{24}\right)}{\left(6.4x10^6\right)^{ }}$

• $\frac{\left(60\right)\left(6x10^{24}\right)}{\left(6.4x10^6\right)^2}$
