Question

Compare and contrast the strength of the forces between two objects with a mass of 1 kg each, a charge of 10

and at a distance of 1 m from each other.

Answer 1

Let's see the similarities between the two forces

* are proportional to the product of a magnitude, mass or charge

* They are inversely proportional to the square of the distance

* They are long-range forces since zero is not made up to an infinite distance. The gravitational force is always attractive, the electrical force can be attractive or repulsive.

The differences in them

* The electric force in much greater than the gravitational force

* The gravitational force is always attractive, the electrical force can be attractive or repulsive.

Step-by-step explanation:

Let's start by calculating each force.

Gravitational force

F =
`G (m_1m_2)/(r^2)`

let's calculate

F = 6.67 10⁻¹¹ 1 1 / 1²

F = 6.67 10⁻¹¹ N

Electric force

F =
`k (q_1q_2)/(r^2)`

indicates that the charge is q = 10 C

F = 9 10⁹ 10 10 / 1²

F = 9 10¹¹ N
