Recently there are some arguments, like Verlindes theory, which showed that gravity emerges as changing the entropy. It means gravity is not a fundamental force any more. Using information storage in the black holes to get a relation between entropy and gravity is very useful way to make this theory reliable. In this book by looking to the job done by Verlinde we study the entropic force of two spacetimes without and with dilaton field, which are the Schwarzschild black hole and the charged dilaton black hole respectively. Generally, the existence of the dilaton field makes over the spacetime...
