Question

A force of 5n applied at the edge of a door produces a moment of force of 4.5 nm. what is the width of the door.

Answer 1

Answer:

We know, torque or moment is a vector quantity and it's given by the product of force and perpendicular distance from the joint.

Here,

Moment of force = 4.5Nm

force applied = 5N

Let the width of the door be x.

= > 4.5 m = 5*x

= > 4.5/5 m = x

= > 45/50 m = x

= > 9/10 m = x

= > 0.9 m = x

Hence, width of the door is 0.9 m
