Answer from: graymonky12

The magnitude of the force between the objects will be four times the initial force.

$\texttt{ }$

Further explanation

Electric charge consists of two types i.e. positively electric charge and negatively electric charge.

$\texttt{ }$

There was a famous scientist who investigated about this charges. His name is Coulomb and succeeded in formulating the force of attraction or repulsion between two charges i.e. :

$\large {\boxed {F = k \frac{Q_1Q_2}{R^2} } }$

F = electric force (N)

k = electric constant (N m² / C²)

q = electric charge (C)

r = distance between charges (m)

The value of k in a vacuum = 9 x 10⁹ (N m² / C²)

Let's tackle the problem now !

$\texttt{ }$

Given:

initial force between objects = F

initial charge of the object = q

final charge of the object = 2q

Unknown:

final force between objects = F' = ?

Solution:

$F : F' = k \frac{q_1 q_2}{(d)^2} : k \frac{q'_1 q'_2}{(d')^2}$

$F : F' = k \frac{q_1 q_2}{(d)^2} : k \frac{2q_1 (2q_2)}{(d)^2}$

F : F' = (q_1 q_2) : (4q_1 q_2)

F : F' = 1 : 4

F' = 4F

$\texttt{ }$

Conclusion:

The magnitude of the force between the objects will be four times the initial force.

Answer from: Quest

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

Answer from: Quest

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
