Question

A nut is opened using a wrench of length 10 cm. If a moment of force of 0.5 N m is developed, then the amount of force required is:

पर्याय

• 5 N

• 10 N

• 0.1 N

• 0.5 N

Answer 1

5 N

Explanation:

Convert units to SI:

The length of the wrench must be in meters.

Length (d) = 10 cm = `10/100` m = 0.1 m

Formula:

Moment of force = Force × Length

0.5 N m = F × 0.1 m

F = `0.5/0.1`

F = 5 N
