The erg is a unit of work in units of centimeters (cm), grams (g), and seconds (s), and 1 erg=1 g⋅cm2/s2 . Recall that the SI unit of force is the newton (N) and is equal to kg⋅m/s2 . You push an object 0.032 m by exerting 0.010 N of force. The work is the force times the distance.

How much work have you done, expressed in ergs?

3,200 ergs

32 ergs

0.32 ergs

0.00032 ergs

Answer:

The work done by the object is 3200 erg.

Explanation:

given that,

Force exerted on the object, F = 0.01 N

The object is pushed to a distance of 0.032 m

We need to find the work done by the object. We know that the force times the distance is equal to the work done. It is given by :

[tex]W=F\times d\\\\W=0.01\ N\times 0.032\ m\\\\W=0.00032\ J[/tex]

We know that,

[tex]1\ J=10^7\ erg[/tex]

So,

[tex]0.00032\ J=3200\ erg[/tex]

So, the work done by the object is 3200 erg. Hence, the correct option is (A).
