Question

The two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). Because of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. (Figure 1) shows the thymine-adenine bond. Each charge shown is ±e, and the HN distance is 0.110 nm .

Calculate the force on the electron in the hydrogen atom, which is 5.29×102 nm from the proton.

Explanation / Answer

Calculate the force on the electron in the hydrogen atom, which is 5.29×10^2nm from the proton.?

5.29×10^2nm =5.29×10^11m

The force on the electron is exerted by the proton, as given by CoulomBS LAW

F= k x q1 x q2 / r^2

=(8.99 x 10^9) (1.602 x 10^-19) (-1.602 x 10^-19) / (5.92 x 10^-11 m)^2

= 8.22 x 10^-8 N ANSWER
