Which statement best describes the gravitational force of an object
the object has gravitational force when it is on the surface of a massive body such as earth
the greater the objects mass the less gravitational force there will be
the greater the objects mass and the closer it is the greater the grav. force
the farther away an object is the greater the grav. force will be

The statement that best describes the gravitational force of an object is: "The greater the object's mass and the closer it is, the greater the gravitational force."
To calculate the gravitational force between two objects, you can use Newton's law of universal gravitation, which states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Now, let's calculate the gravitational force of the robotic helicopter on Mars. To do this, we need to know the mass of the helicopter on Mars and the distance between the helicopter and the surface of Mars. However, this information is not given in the question, so we cannot determine the exact value.
Therefore, we cannot determine the precise gravitational force of the helicopter on Mars with the information provided.
The gravitational force of an object is directly proportional to its mass, and it is inversely proportional to the square of the distance between the objects. Therefore, the statement that best describes the gravitational force of an object is: "The greater the object's mass and the closer it is, the greater the gravitational force."
Regarding the second question, to determine the helicopter's gravitational force on Mars, we need to know the mass of the helicopter and the mass of Mars.
Given that the gravitational force on Earth is 1.8 newtons, and assuming the mass of the helicopter remains constant, the gravitational force on Mars can be calculated using the formula:
Gravitational force on Mars = (mass of helicopter on Mars / mass of helicopter on Earth) * gravitational force on Earth
Since we don't have the mass of the helicopter or the mass of Mars, it's not possible to provide a specific answer.
