** CONCEPT**:

**Force**: A force is a push or pulls upon an object resulting from the object's interaction with another object.- Whenever there is an interaction between two objects, there is a force upon each of the objects.

**Unit of force:**The second law of motion proposed by Newton, force is defined or expressed as the product of mass and acceleration.

** EXPLANATION**:

- In the
**CGS system of units**, the unit of mass is gram or g, and the unit of**acceleration is cm/s**Therefore, the CGS unit of force is g cm/s^{2}.^{2}. which is**called dyne**or**Dyn**. **One dyne is equal to 10 μN**(micro-newtons) or to 10 nsn (nano-sthenes) in the old meter-tonne-second system of units. Equivalently, the dyne is defined as "the force required to accelerate a mass of gram at a rate of one centimeter per second squared".- Hence option 2 is the answer.
