Biophysicists use an arrangement of laser beams called optical tweezers to manipulate microscopic objects. In a particular experiment, optical tweezers exerting a force of 0.373 pN were used to stretch a DNA molecule by 2.30 μm.What was the spring constant of the DNA?

Experiments using "optical tweezers" measure the elasticity of individual DNA molecules. For small enough changes in length, the elasticity has the same form as that of a spring. A DNA molecule is anchored at one end, then a force of 1.5 nN (1.5 times 10^-9 N) pulls on the other end, causing the molecule to stretch by 5.0 nm (5.0 times 10^-9 m),as shown in the figure.(p.s. The source of the external force is the laser beam that traps and...
