One Newton force, is A. 103 dynes B. 104 dynes C. 105 dynes D. 106 dynes

The correct answer is: 105 dynes.

A dyne is a unit of force in the centimeter-gram-second (CGS) system of units. It is defined as the force required to accelerate a mass of one gram at a rate of one centimeter per second squared.

One Newton is equal to 105 dynes. This can be written as:

1 N = 105 dynes

To understand this, we can consider the following example. If we have a mass of 1 gram and we want to accelerate it at a rate of 1 centimeter per second squared, then we need to apply a force of 105 dynes.

The other options are incorrect because they do not represent the correct conversion factor between Newtons and dynes.
