Random pause of 2 to 5 seconds between requests Jmeter

Question

I need to make a random pause of 2 to 5 seconds between requests. I suppose, that it is a constant timer with such settings as ${__Random(2000,5000)}. I can't understand where should I create this timer: in thread group after all requests, or after every request in thread group? How can I check via listeners, that timer works correctly?
Thanks to Amol, I understood, that my config doesn't work with multiple threads.
So I need 10 threads and 10 iterations with a random pause of 2 to 5 seconds between requests.

If you want to have a random pause between every request, you need to add timer as 'sibling' to your samplers [requests], that means add constant timer as a child to thread-group.
How to use Constant Timer for random pause-

It won't make any difference if you add it as a first child or after all samplers. For better understanding, I suggest you to read scoping in Jmeter
Example here:-

You can easily see the randomness requests being made using View Results in Table. it has Start Time column which gives idea.
I have used debug sampler for example again:

Hope this helps.
EDIT:-
If I disable the constant-timer, I can see all the request being made in the span of 1ms:
