Answer #1

if the force between ions on either ends of the DNA molecule =F the seperation between eithe ends after compression ( 1-1 .31 %): 2. I 8um r r 2.15le- 06 m coloumb constant c-8.98x 10 N.mC q1.602e-19C we plug the values in hand, while using the relation F-4.986e-017N 2 -2 if the spring force constant of DNA is -k and DNA compressed distance Ax-1.31%): 2. I 8μm-2.856e-008 m F kAx ;weplug the values in hand while using the relation give us 1.746e-09
