The electric flux on a surface of area A in a uniform electric field E is given by 
φ = EA cos θ
where θ = the angle between the directions of E and a normal vector to the surface of the area.
See the diagram shown below.
When the electric field is perpendicular to the surface, then θ = 0°, and
φ = EA cos(0°)  = (6.20 x 10⁵ N/C)*(3.2 m²) = 1.984 x 10⁶ (N-m²)/C
When the electric field is parallel to the area, then θ = 90°, and
φ = EA cos(90°) = 0
Answer:
(a) 1.984 x 10⁶ (N-m²)/C
(b) 0
 
        
        
        
Answer:compound is a poly element pure substance
Explanation:
It made up of two or more elements.
It can be broen down into simpler units
 
        
             
        
        
        
A diod can act as a capacitor
the deplition region in diod acts as a capacitor as it also stores energy similar to capacitor in electric field.
 
        
             
        
        
        
No, we cannot touch gravity nor can we physically see it. We can only see how it works.
        
             
        
        
        
Answer:
Magnetic field, 
Explanation:
Given that,
Velocity of electron, 
It enters  a region of space where perpendicular electric and a magnetic fields are present.
Magnitude of electric field, 
We need to find the magnetic field will allow the electron to go through the region without being deflected. 
Magnetic force on the electron,  .......(1)
.......(1)
Electric force on the electron, F = q E........(2)
From equation (1) and (2) we get:



B = 0.0002 T
or

Hence, this is the required solution.
