Solution
The expression for the gravitational force of attraction between the two masses in Newtons is -
F = G m?m?/r²
where,
G = 6.674e-11 m³/kgs²
m? and m? are the masses of the two objects in kg r is the distance in meters between their
centers
#1, at +x = 3?2 meter distance
F1 = G(5)² / (3?2)² = 1.39*G
angle is 0º
#2 at distance 1 meter
F2 = G(5)² / (3)² = 2.78*G
angle is 45º
#3 at distance 1 meter
same as F2 but angle is –45º
Y components of 2 and 3 cancel, so all we have to do is add the x components
F = F1 + F2cos45 + F3cos45
F = F1 + 1.414 F2
F = 1.39*G + 1.414*2.78*G = 5.32*G = 5.32*6.674*10^-11 = 3.55 x 10^-10 N
