¿Cuál es la distancia a la que debemos colocar dos cargas puntuales, q1 = 4 µC y q2 = -4 µC, para que se atraigan con una fuerza de 4.8 N?

Lo necesito porfavor

The probability of getting all 5 right would be 1/3125

This is because each question has one choice. Making it a 1/5 chance for each question. 

Now if you combine if you add the rest you will have to calculate.

You would do the calculation by multiple the chance for a correct answer for each question together.

1/5 x 1/5 x 1/5 x 1/5 x 1/5 = 1/3125

I hope this helped!
