The gravitational force is s type of force that has the ability to attract any two objects with mass. Gravitational force tries to pull two masses towards each other.
Given,
mass of the sun ()=
kg
mass of Jupiter()=
kg
distance between the sun and Jupiter (r)= m
Newton
Hence the gravitational force between the sun and Jupiter will be

Answer:
, repulsive
Explanation:
The magnitude of the electric force between two charged particles is given by Coulomb's law:
where:
is the Coulomb's constant
are the two charges of the two particles
r is the separation between the two charges
The force is:
- repulsive if the two charges have same sign
- Attractive if the two charges have opposite signs
In this problem, we have two electrons, so:
is the magnitude of the two electrons
is their separation
Substituting into the formula, we find the electric force between them:
And the force is repulsive, since the two electrons have same sign charge.
Answer:
The angle from vertical of the axis of the second polarizing filter is 50.57⁰.
Explanation:
Given;
intensity of the unpolarized light, I₀ = 300 W/m²
intensity of emergent polarized light, I = 121 W/m²
let the angle from vertical of the axis of the second polarizing filter = θ
Apply Malus's law, intensity of emergent polarized light is given as;
I = I₀Cos²θ
Therefore, the angle from vertical of the axis of the second polarizing filter is 50.57⁰.
