Answer:
If a Gaussian surface is completely inside an electrostatic conductor, the electric field must always be zero at all points on that surface.
Explanation:
Option A is incorrect because, given this case, it is easier to calculate the field.
Option B is incorrect because, in a situation where the surface is placed inside a uniform field, option B is violated
Option C is also incorrect because it is possible to be a field from outside charges, but there will be an absence of net flux through the surface from these.
Hence, option D is the correct answer. "If a Gaussian surface is completely inside an electrostatic conductor, the electric field must always be zero at all points on that surface."
 
        
             
        
        
        
Answer:
The distance covered by puck A before collision is  
Explanation:
From the question we are told that 
    The label on the two hockey pucks is  A and  B 
     The distance between the  two hockey pucks is D   18.0 m 
      The speed of puck A is  
         The speed of puck B is  
The distance covered by puck A is mathematically represented as 
      
   =>  
  The distance covered by puck B  is  mathematically represented as 
       
=>   
Since the time take before collision is the same 
         
substituting values 
           
=>      
=>       
 
 
        
             
        
        
        
The answer would be A because
