The Attempt at a Solution

I have a question about exercise c. The flux Q is the integral, isn't it? So why do they use the word "then"?

 

[dirk_mec1]

I think that the question isn't correctly posed. I think it should be like this:

"Calculate the flux Q throught the slit... width in other words evalute the integral".

Is this correct?

I can understand your confusion about the use of the word "then" in this exercise. However, in this context, the word "then" is not referring to the integral itself but rather to the process of finding the integral. In other words, the sentence is saying that if you understand how to find the integral, then you can use that knowledge to solve this particular problem. The use of "then" is simply indicating a logical sequence of steps in solving the problem. I hope this clarifies any confusion you may have had.
