Biophysicists use an arrangement of laser beams called optical tweezers to manipulate microscopic objects. In a particular experiment, optical tweezers exerting a force of0.373 pN were used to stretch a DNA molecule by 2.30 μm. What was the spring constant of the DNA?Express your answer with the appropriate units.

Hence, the spring constant is equal to

Explanation:

As we know that

----------Equation (1)

Where F is the force

K is the spring constant and

x is the displacement of the spring on application of force F

Given

pico Newton

Newton

Displacement  of the spring micro meter

meter

Substituting the given values in above equation (1), we get -

Hence, the spring constant is equal to

is in the form atp or adenosine triphosphate
