Question

The attached figure shows "The dependence of electric field strength on the distance & its relation to the number of field lines."
But what does it actually want to say? I can't understand:(
Please help me in understanding this point:)

Answer 1

It means: the denser the lines, the stronger the field; and vice-versa.

Answer 2

Sory for being late. I will post it tomorrow:)

Answer 3

the figure says that denser the field lines stronger the electric field. As the field lines becomes rarer the electric field becomes weaker and weaker.
