Fetch Data of Different Organization?

Question

I have 2 Orgs- Org A & Org B both are ap1 Instance

In Org A I've created a Connected app

In Org B I am trying to Query accounts of Org A From the Connected App Through Http Call, but I am getting the Data of Org B Itself

Is it Because of same Instance of Endpoint Url

Below is My Http Class After Getting the Access Token

 http h = new Http();
 HttpRequest eq1= new HttpRequest();
 eq1.setMethod('GET');
 eq1.setEndpoint('https://ap1.salesforce.com/services/data/v33.0/query?q=SELECT+id,name,type,description,industry+FROM+account+ORDER+BY+name');

eq1.setHeader('Content-Type', 'application/xml');
//eq1.setHeader('Authorization', acc);
eq1.setHeader('Authorization', 'OAuth '+acc);
Httpresponse hh1 = new HttpResponse();
hh1 = h.send(eq1);
