Question

The electrostatic
between two point charges is
The charge on each point charge is doubled and the distance between charges is
halved. What is the new force between them?

Answer 1

Resposta:

Explicação passo-a-passo:

The first Force is: Fel= K.Q.Q/d^2

Now, the new force, I called Force 2, is : Fel2 = K(2Q).(2Q)/0,25d^2

Fel2 = 4 [ K(2Q).(2Q)/d^2 ]

Look at this : Fel1 = K(2Q)(2Q)/d^2

Finally, we have : Fel2 = 4.Fel1
