What happens to the force between two charged objects when you triple the magnitude of both charges?

Vika [28.1K]

If the force between two charged objects when you triple the magnitude of both charges. The Force will become 9 times the initial force.

<h3>What is coulombs law?</h3>

According to coulombs law force between two charges is given by

$F = \dfrac{1}{4\pi \epsilon }\dfrac{Qq}{r^2}$

Here, R is the distance between both the charges Q and q.

Let the force on the charges be F1

The distance of separation = r

The magnitudes of the charges q1 and q2

K = Coulumb's constant

$F = \dfrac{1}{4\pi \epsilon }\dfrac{Qq}{r^2}$

Let the force on the charges be F

The distance of separation = r

The magnitudes of the charges 3q1 and 3q2

K = Coulumb's constant

So,

$F = \dfrac{1}{4\pi \epsilon }\dfrac{Qq}{r^2}$

$F = \dfrac{1}{4\pi \epsilon }\dfrac{3Q\times 3q}{r^2}\\\\F = \dfrac{1}{4\pi \epsilon }\dfrac{9Qq}{r^2}\\\\F =9 \dfrac{1}{4\pi \epsilon }\dfrac{Qq}{r^2}\\\\F = 9F_1$

Write the following improper fractions as mixed number or a whole number 28/3

kolbaska11 [484]

Answer: 9 and 1/3

Step-by-step explanation: To write an improper fraction as a mixed number, we divide the denominator into the numerator.

In this case, we divide 3 into 28.

3 divides into 28 nine times with a remainder of 1.

In other words, 9 wholes and 1 out of 3.

Ava estimates that 475 songs will fit on her iPad. The actual amount of songs that fit is 350. Find her percent of error.

alukav5142 [94]

Given:

Ava estimates that 475 songs will fit on her iPad.

The actual amount of songs that fit is 350.

To find:

The percent of error.

Solution:

We know that,

$\text{Percent error}=\dfrac{\text{Estimated values - Actual value}}{\text{Actual value}}\times 100$

Putting the given values, we get

$\text{Percent error}=\dfrac{475-350}{350}\times 100$

$\text{Percent error}=\dfrac{125}{350}\times 100$

$\text{Percent error}=\dfrac{250}{7}$

$\text{Percent error}\approx 35.71\%$

Therefore, the percent of error is 35.71%.
