Answer:
Thickness of each page will be 0.00785 cm
So option (E) will be correct answer
Explanation:
We have given that last page on the book is numbered as 764
So total number of pages in the book
( as each page is numbered in both side )
Total thickness of the book = 3 cm
We have to found the thickness of the each page
So thickness of each page will be 
So option (E) is correct option
Explanation:
By introducing a particle of one positive coulomb between the electric plates, the particle experience a force against the electrostatic forces, proving that it is in an electric field
The force experienced by this particle is known as <em><u>Electric</u></em><em><u> </u></em><em><u>Field</u></em><em><u> </u></em><em><u>Intensity</u></em><em><u> </u></em> denoted by <em><u>E</u></em><em><u> </u></em>and it is given by

where, k is constant =

q is the charge magnitude on the particle
r is the separation of the particles
