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.
