There is a force of gravity acting downward on the object,
and no force acting upward on it.
Since the vertical forces on it are unbalanced, it accelerates
in the direction of the net vertical force, which is downward.
Sunlight and wind because they never run out
Answer:
a = 3.21 10⁻⁸ m / s²
, The correct answer is E
Explanation:
For this exercise we will use Newton's second law, where the force is the gravitational attraction force, the attached diagram shows the forces and their components in a horizontal and vertical coordinate system, due to the symmetry of the equilateral triangle the horizontal components be annulled and the two vertical components add up; let's write Newton's education for the vertical axis (Y)
2 = m a
Let's use trigonometry to find the components
sin 60 = / F
= F sin60
2 F sin60 = m a
The gravitational force equation is
F = G m M / r
The mass of the entire sphere is equal to m = M and the distance between the spheres is the side of the equilateral triangle
F = G m² / L²
We replace
2 (G m² / L²) sin60 = m a
a = 2 G m / L² sin 60
Let's calculate
a = 6.67 10⁻¹¹ 50 / 0.30² sin 60
a = 3.21 10⁻⁸ m / s²
The correct answer is E
A triangle is the symbol used to indicate a fulcrum in a lever, a triangle has three sides and three vertices.
<h3>What is a fulcrum?</h3>
A fulcrum is a pivot that has a base and a point that serves as a balance for a lever.
<h3>What is a lever?</h3>
Basically a lever is a simple machine that is a beam with two sides pivoted to fulcrum.
A lever has Load, Effort and the last part is fulcrum
