Answer:
Explanation:
mass of top book = 2kg
mass of book under = 3kg
mass of table = 20kg
a) The diagram is in the attached file to this solution
b) Since the objects are at rest, the acceleration of each of the object is zero
c) Force of gravity giving that g = 10 is
for the top book = 2*10 = 20N
for the book under = 3*10 = 30N
for the table = 25*10 = 250N
d) for the top book = 2*10 - 2*10= 0N
for the book under = 3*10 - 3*10 = 0N
for the table = 25*10 - 25*10 = 0N
