Answer:
The point that would have the same electric field as P is   from the center of the sphere.
 from the center of the sphere.
Explanation:
From the question we are told that 
   The  radius of the sphere is  
    The Electric field at point P is   
  
     The distance of point P from the center is  
 
Since the electric is directed radially outward it mean this it would be felt both inside and outside the sphere 
 The Electric field inside the sphere at a distance z is mathematically represented as
             
where k is the coulomb's constant with a  value 
             q is the charge 
               
The Electric field inside the sphere at a distance D  is mathematically represented as            
                 
To obtain the point of equal electric field 
            
           
  We have that 
              
Substituting values 
                 
                 
 
        
             
        
        
        
Answer:
O B. when the angle between the force and displacement is 90°
Explanation:
<h3>work defined as   

. </h3><h3>work  can only be done if object moves(displacement) in the direction of force. now a quick one. if you since the varrious angles into the cosine, you would see that Cos 90 will give zero which implies that no work is done. Again, angle means it is perpendicular and so it is not in the direction of force.</h3>
 
        
             
        
        
        
Answer:
