Answer:
the moment of force is 25 Nm.
Explanation:
Given;
weight of the book, F = 50 N
distance through which his hand was stretched, d = 50 cm = 0.5 m
The moment of force is calculated as;
moment of force = F x r
moment of force = 50 N x 0.5 m
moment of force = 25 Nm
Therefore, the moment of force is 25 Nm.
