A spring balance reads forces in Newton. The scale is 20 cm long and read from 0 to 60 N. Find potential energy of spring when the scale reads 20 N.

A spring balance has a scale that reads from 0 to 50 kg. The length of the scale is 20 cm. A body suspended from this spring, when displaced and released, oscillates with a period of 0.6s. What is the weight of the body? When 50 kg is put, the extension of spring is 20 cm.
