Question

What is the force constant k of a spring which is stretched
2 mm by a force of 4 N,
4 cm by a mass of 200 g?

Answer 1

Answer:

Two springs X and Y have spring constants k and 2k respectively.Spring X is stretched by a force F and spring Y is stretched by a force 2F. Each spring obeysHooke’s law during the extension.The work done in stretching spring X is WX and the work done in stretching spring Y is WY.What is the relationship between WX and WY?[1] 1A WY =WX2B WY = WXC WY = 2WXD WY = 4WX
