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

Answer:

first mark as brainliest

Explanation:

Given

r=25cm=.25m

Momentum=4nm=4*10^-9

Momentum=F*r

F=momentum/r

F=16 nm

Answer 2

As we know ,

Mumentum = Force × displacement

Force = Mumentum / Distance

Force = (4× 100)/25

= 4×4

= 16 N
