Two elastic load-securing straps, M and N, both obey Hooke’s law over the range tested. At an extension of 0.050 m, strap M exerts a force of 15 N and strap N exerts a force of 10 N.
Which statement correctly compares the straps?
The spring constants are 15 N for strap M and 10 N for strap N.
Strap M has a greater spring constant than strap N.
Strap N has a greater spring constant than strap M.
The straps have the same spring constant because both are elastic.
