We can find the y-component of the resultant force by adding the y-components of the two 20N forces.
For a force of magnitude F and lying at an angle off the x-axis θ, the y-component of the force is given by:
Fsin(θ)
The magnitude of the two forces is 20N, and they lie at 30° and 60°, so the sum of their y-components, and therefore the y-component of the resultant force, is:
20sin(30°)+20sin(60°)
= 27.3N
The equigravity between two planets is determined from the product and their masses and square of distance between them.
<h3>Gravitational force between two planets</h3>
The gravitational force between two planets is calculated as follows;
F = GM₁M₂/R²
where;
- G is universal gravitation constant
- M₁ is mass of first planet
- M₂ is mass of the second planet
- R is the distance between the two planets
Use the mass ratio of the two planets to determine their individual masses.
Thus, the equigravity between two planets is determined from the product and their masses and square of distance between them.
