If a force of 50 N stretches a wire from 20 cm to 20.01 m , what is the amount of force required to stretch the same material form 20 m to 20.05 m

Answer 1

To calculate the force required to stretch the wire from 20 m to 20.05 m, we can first calculate the force per unit length required to stretch the wire from 20 cm to 20.01 m.

Force per unit length = Force / Original length
Force per unit length = 50 N / 0.20 m
Force per unit length = 250 N/m

Now, we can calculate the force required to stretch the wire from 20 m to 20.05 m.

Force = Force per unit length x Change in length
Force = 250 N/m x 0.05 m
Force = 12.5 N

Therefore, the amount of force required to stretch the wire from 20 m to 20.05 m is 12.5 N.
