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

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 :

We know that,

So,

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

i don't know that i agree with that but what's the question ?
