Answer:
Supongo que este es un problema de fuerza gravitatoria.
Sabemos que la fuerza gravitatoria entre dos objetos, uno de masa M1 y otro de masa M2, que están separados por una distancia R, es:
F = G*(M1*M2)/R^2
Donde G es la constante de la gravitación universal.
G = 6.674*10^(-11) N*m^2/kg^2
Y sabemos que;
M1 = 60kg
M2 = 80kg
R = 2m
Reemplazando eso en la ecuación obtenemos:
F = ( 6.674*10^(-11) N*m^2/kg^2)*(60kg*80kg)/(2m)^2 = 8.01*10^(-8) N
Esta es la fuerza gravitacional entre los dos objetos.
Tenga (subjunctive mode in the subordinate clause of "que mi padre....", because you are hoping this will happen, but there is uncertainty it will.)
