where can i earn $5 to $10 without investment

Try postloop, you will have to post a lot in forums but its pretty easy. It can take some people less then a week to make $5 on postloop. Good Luck and if you have more questions just ask. :)

If you do swagbucks.com and average 140 swagbucks a day you could redeem them for $5 in paypal cash each week (I mean this literally over a 5 day period). If you were okay with $5 in Amazon e-gift cards than all you would need to do is earn 90 swagbucks over 5 days. You could look into it if interested

If you are good at writing, both academic and non-academic pieces, then consider joining Odesk, Guru and Elance freelance sites. You can also try with some micro freelance sites where you need to create a job and post it. If a client wants the service you are willing to provide that you have mentioned in the job or post, you can make easily $5 day. However, you have to work hard at it in getting $5 day. Write with a few upfront and residual income generating sites, keep posting at Mylot, etc. On an average you will have earned more than $5 day then.

Remember one thing there is no shortcut.You have to work hard for earning 5-10$ in very little time.You can do work in http://www.freelancer.com this site is based on freelansing type.Or you can earn money by posting here quality post .

Actually there is a site that will pay you that much in a short time, but it is the freelance kinds site, people post their problems and those who answer/finish the task they get payed from 1$ up to 100$ or more. So check it out http//:www.studentoffortune.com
