Answer: D
Step-by-step explanation:
Given information:
Semi truck mass M = 20000kg
Car mass m = 2000 kg
Distance d = 10 m
G = (0.667 10-11 N•m²/kg)
The gravitational force between them can be expressed as
F = GMm/r^2
Substitute all the parameters into the formula
F = (0.667 10-11 × 20000 × 2000)/ 10^2
F = 2.668×10^-4/100
F = 2.668 × 10^-6 N
Therefore, the force of gravity between them is 26.7 × 10 ^-5 N approximately
