Answer 1

Hey friend , Harish here.

Here is your answer

__________________________________________________________

$Time period = 0.002 sec$
 
                    $= \frac{2}{1000}$

$frequency = \frac{1}{time period}$
                     
                 $= \frac{1}{ \frac{2}{1000} }$
   
                $= \frac{1000}{2}$
            
               $= 500 Hz$
