Question

The moment of a force of 5 N about a point P is 2 N m. Calculate the distance of point of application of the force from the point P.​

Answer 1

★ Given :

• ➻ Moment of Force = 2 N m
• ➻ Force (F) = 5 N

★ Find :

• ➻ Distance (r)

★ Solution :

✠ If the distance of the point of application of force from the point P is r metre, then :

• ➣ Moment of force = force ༝ distance

• ➣ 2 = 5 ༝ r
• ➣ r = 2/5
• ➣ r = 0.4 m

❍ Therefore,

• Hence, the distance (r) is 0.4 m.

Answer 2

Given :

• Moment of force = 2 Nm
• Force, F = 5 N

To Find :

• Distance, r = ?

Solution :

We know that :

✧ [Moment of force = Force × Distance]

By substituting values :

=> 2 Nm = 5 N × r

=> r = 2/5

=> r = 0.4 m

Hence, distance = 0.4 m.
