Question

Julie can open a 2 m wide door by a
minimum force of 2.5 N. Find the
moment of force needed to open the door.

Answer 1

Answer:

To open the door, 5 Nm moment of force is needed.

Explanation:

Here,

the applying force = 2.5 N

& the distance from the applying force to the door = 2m

We all know,

Moment of force = force× distance

that is, = 2.5 N × 2m

= 5 Nm

Answer 2

Answer:

Solution : Given, force F = 2.5 N, distance

d = 2 m

Moment of force = Fx d = 2.5 N x 2 m = 5.0 N m
