The nucleotides attach to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands. Genes are short pieces of DNA that carry specific genetic information.

two charges attract each other with a force of 1.2 * 10⁻⁶N. Calculate the force that would act between the two charges when dist

Likurg_2 [28]

1. When the distance is doubled: $3\cdot 10^{-7}N$

The electrostatic force between two charges is given by:

$F=k\frac{q_1 q_2}{r^2}$

where

k is the Coulomb's constant

q1 and q2 are the two charges

r is the distance between the two charges

The initial force between the two charges is $F=1.2\cdot 10^{-6}N$ . In this part of the problem, the distance between the two charges is doubled, so we can write

$r'=2r$

And substituting into the formula, we find the new force:

$F'=k\frac{q_1 q_2}{r'^2}=k\frac{q_1 q_2}{(2r)^2}=\frac{1}{4}k\frac{q_1 q_2}{r^2}=\frac{F}{4}$

So, the force is reduced to 1/4 of its original value. Therefore, it is

$F'=\frac{1.2\cdot 10^{-6} N}{4}=3\cdot 10^{-7}N$

2. When the distance is halved: $4.8\cdot 10^{-6}N$

The initial force between the two charges is $F=1.2\cdot 10^{-6}N$ . In this part of the problem, the distance between the two charges is halved, so we can write

$r'=r/2$

And substituting into the formula, we find the new force:

$F'=k\frac{q_1 q_2}{r'^2}=k\frac{q_1 q_2}{(r/2)^2}=4k\frac{q_1 q_2}{r^2}=4F$

So, the force is quadrupled. Therefore, it is

$F'=4(1.2\cdot 10^{-6} N)=4.8\cdot 10^{-6}N$

3. When the distance is tripled: $1.33\cdot 10^{-7}N$

The initial force between the two charges is $F=1.2\cdot 10^{-6}N$ . In this part of the problem, the distance between the two charges is tripled, so we can write

$r'=3r$
