Gravity is defined as the force of attraction between all masses in the universe, gravity is what allows the sport of climbing.
it would be C laminated soda lime glass
Answer:
Energy will be 
Explanation:
We have given that dielectric constant k = 5
Area of the plate 
Distance between the plates 
Electric field E = 200 kN/C
We know that capacitance is given by 
We know that electric field is given by 
So 
So energy will be
