Question

The hinge of a door is at a distance of 25 cm from the point of application of force. How much force must be applied so that it produces the moment of force of 4 Nm?

Answer 1

As we know ,

Mumentum = Force × displacement

Force = Mumentum / Distance

Force = (4× 100)/25

= 4×4

= 16 N

Answer 2

Solution:

As we know ,

Moment of force = Force × Distance

Then,

Force = Moment of force / Distance

$Force = (\frac{100}{4} ) \times 25$

$= (4\times4) N$

$= 16 N$
