A weight of 4.0 N is used to extend a spring. The extension of the spring is 0.06 m. (i) Calculate the spring constant, k, of the spring. (ii) State what measurements should be made to determine the extension of the spring produced by the 4.0 N weight.

See explanation

Explanation:

Hookes law states that; the displacement due to a stretching force is directly proportional to the magnitude of the deforming force.

F = ke

F = deforming force

k = force constant

e = extention

k = F/e

k = 4N/0.06 m= 66.67 Nm^-1

To determine the extension of the spring produced by the 4.0 N weight

1) We measure the original length of the spring

2) We measure the length after hanging the 4 N mass

3) Subtract the new length from the original length to determine the extention.
