Which querry will give more performance

[getmeidea]

I have the following tables,

1> employee_master (emp_id int primary key, emp_name varchar(100));
2> employee_salary _payment(salary _rid int primary key, emp_id int, sal_date date, paid_amt int);

The tables, employee_master and employee_salary _payment have one to many relation.
I need to list the salary payment done for the employee having id = 10. Here I use two different querry to work.

Querry 1:

Select em.emp_id, em.emp_name, esp.sal_date, esp.paid_amt
from employee_master em join employee_salary_payment esp
on (em.emp_id = esp.emp_id and em.emp_id = 10);

Querry 2:

Select em.emp_id, em.emp_name, esp.sal_date, esp.paid_amt
from employee_master em join employee_salary_payment esp
on em.emp_id = esp.emp_id
where em.emp_id = 10;

Question:
Both the querry will give the same performance?
If no, what is the reason?
