Answer:

Explanation:
The electric flux through a certain surface is given by (for a uniform field):

where:
E is the magnitude of the electric field
A is the area of the surface
 is the angle between the direction of the field and of the normal to the surface
 is the angle between the direction of the field and of the normal to the surface
In this problem, we have:
 is the electric field
 is the electric field
L = 2.0 m is the side of the sheet, so the area is

 , since the electric field is perpendicular to the surface
, since the electric field is perpendicular to the surface
Therefore, the electric flux is

 
        
             
        
        
        
Answer:
F' = F
Explanation:
The gravitational force of attraction between two objects can be given by Newton's Gravitational Law as follows:

where,
F = Force of attraction 
G = Universal gravitational costant
m₁ = mass of first object
m₂ = mass of second object
r = distance between objects
Now, if the masses and the distance between them is doubled:

<u>F' = F</u>
 
        
             
        
        
        
I’m pretty sure u have it right
