Answer:
towards the mass 
Explanation: We know that the gravitational force is a long range force which is always attractive in nature.
Given that:
- mass

- mass

- mass

The masses are positioned on X-axis at the following points:
- Position of mass

- Position of mass

- Position of mass

Mathematically:
<em>Gravitational force on mass </em>
<em> due to mass </em>
<em> is given by </em>
...................(1)
- where:
= the radial distance between masses
&
=3
Similarly, g<em>ravitational force on mass </em>
<em> due to mass </em>
<em> is given by </em>
............................(2)
- where:
= the radial distance between masses
&
=3
Now, put the respective values in the above equations.


Again,


∵Mass
is in the middle of the masses
&
therefore the forces
&
will attract them in radially opposite direction.
∴
towards the mass 
Answer:
length of the ladder is 13.47 feet
base of wall to latter distance 6.10 feet
angle between ladder and the wall is 26.95°
Explanation:
given data
height h = 12 feet
angle 63°
to find out
length of the ladder ( L) and length of wall to ladder ( A) and angle between ladder and the wall
solution
we consider here angle between base of wall and floor is right angle
we apply here trigonometry rule that is
sin63 = h/L
put here value
L = 12 / sin63
L = 13.47
so length of the ladder is 13.47 feet
and
we can say
tan 63 = h / A
put here value
A = 12 / tan63
A = 6.10
so base of wall to latter distance 6.10 feet
and
we say here
tanθ = 6.10 / 12
θ = 26.95°
so angle between ladder and the wall is 26.95°
Answer:
q₃ = -4.81 nC
Explanation:
We can use the Gauss Law here:
∅ = q/∈₀
where,
∅ = Net Flux = - 216 N.m²/C
q = total charge enclosed inside sphere = ?
∈₀ = permittivity of free space = 8.85 x 10⁻¹² C/N.m²
Therefore,
- 216 N.m²/C = q / 8.85 x 10⁻¹² C²/N.m²
q = (-216 N.m²/C)(8.85 x 10⁻¹² C²/N.m²)
q = - 1.91 nC
So, the total charge will be sum of all three charges:
q = q₁ + q₂ + q₃
- 1.91 nC = 1.74 nC + 1.16 nC + q₃
q₃ = - 1.91 nC - 1.74 nC - 1.16 nC
<u>q₃ = -4.81 nC</u>
