Answer:
The net force on the 20kg mass m1 is equal to 6.09 x 10^-7 N. This force is due to the sun of the vertical components of the forces F1 and F2 of the masses m2 and m3 respectively on the mass m1.
The law of gravitational force has been applied and the use of the Pythagorean theorem also used.
Explanation:

The magnitude of the net gravitational force on the masses can be determined using Newton's law when the distance between the two masses is known.
Magnitude of gravitational force
The magnitude of gravitaional force on the two given masses can be determined by applying Newton's law of universal gravitation as shown below;
F = Gm₁m₂/r²
where;
- G is universal gravitation constant
- r is the distance between the two masses
- m₁ is the first mass
- m₂ is the second mass
Thus, the magnitude of the net gravitational force on the masses can be determined using Newton's law when the distance between the two masses is known.
