dexar [7]

Given :

The distance between a point charge and a neutral atom and is multiplied by a factor of 5.

To Find :

By what factor does the force on the neutral atom by the point charge change.

Solution :

We know, electrostatic force between two object is directly proportional to product of charge and inversely proportional to distance between them.

Now, charge in neutral atom is 0 C.

So, the electrostatic force between two of them is also 0 N.

Therefore, by changing distance between the charge the forces did no change ( it remains zero).

When rolling a number cube 500 times, how many times you expect to get a 3?
andreyandreev [35.5K]

Answer:

\frac{250}{3}

Explanation:

you can expect to get a 3 (theoretically) 1 time every 6 times you roll. A 1/6 chance.

Here's the equation:

\frac{1}{6} =\frac{x}{500}

cross multiply (i think that's what it is called)

500=6x

divide by 6 on both sides:

x=\frac{250}{3} or approx 83 times.

Hope this helps! Lmk if u have more questions <3
