Question

A load of 80N extends a spring by 8cm. When the load is replaced by a copper block, the extension produced is 10cm. Calculate the weight of the copper block, assuming that the elastic limit of the spring is not exceeded.

Answer 1

x/10 = 80/8

Answer 2

I need the calculation and the answer

Answer 3

F=ke right? So we are looking for f2 where f1 = 80N, e1 = 8cm and e2 = 10cm :. k= f/e then we have f1/e1 = f2/e2 :. We have 80/8=x/10 where x = 100
