a boy Held a book of weight 50 newton’s in his fully outstretched hand, at a distance of 50 cm away calculate the moment of force

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.

probably not if net force is zero
