Why don't you feel a gravitational force from the text book you're reading? 

 

Expert Solution
Step 1

according to newton law if gravitation 

every object exerts gravitational force on the other object 

if the mass of 1 object is m and other is M  and botb are separated by distance d 

then gravitational force b/w them is given by 

F = GmM/d2 

where 

G = univarsal gravitation const = 6.67 x 10-11  Nm2/kg2
