Two objects attract each other with a gravitational force of magnitude 1.02 10-8 N when separated by 19.7 cm. If the total mass
of the two objects is 5.14 kg, what is the mass of each
2 answers:
Answer:
The two masses are 3.39 Kg and 1.75 Kg
Explanation:
The gravitational force of attraction between two bodies is given by the formula;
F = Gm₁m₂/d²
where G is the gravitational force constant = 6.67 * 10⁻¹¹ Nm²Kg⁻²
m₁ = mass of first object; m₂ = mass of second object; d = distance of separation between the objects

Explanation:
The period of a simple pendulum is given by:
where L is the length of the pendulum and g is the free-fall acceleration on the planet.
Calling L the length of the pendulum, we know that:
is the period of the pendulum on Earth, and
is the free-fall acceleration on Earth
is the period of the pendulum on Mars, and
is the free-fall acceleration on Mars
Dividing the two expressions we get
And re-arranging it we can find the value of the free-fall acceleration on Mars:
