Concept: A system of standard units is the C.G.S. The abbreviation CGS stands for centimeter-gram-second. The amount of work performed by a force of one dyne to move a distance of one cm is known as the C.G.S system's work. The complete formula for the quantity must be changed to correspond to the specific standard system in order to find any unit in that system.
Only when the object is moved in the direction of the force is a task considered completed. The applied force and displacement product can be used to calculate the overall amount of work.
The joule is the SI unit of labor. To move an object one meter with a force of one newton, it takes one joule of labor.
In the CGS system, the erg serves as the unit of work. The work required to move a force of one dyne one cm is known as an erg.

1 Joule = 10^{7} erg

Hence, the correct option is 3.
