Question 1: A load suspended by a massless spring produces an extension of x cm in equilibrium. When it is cut into two unequal parts the same load produces an extension of 7.5 cm when suspended by the large part of length 60 cm. When it is suspended by the smaller part the extension is 5.0 cm. then:

x = 12.5

x = 3.0

the length of the original spring is 90 cm

the length of the original spring is 80 cm
