Question

A spring 25cm long is stretched to 30cm by a load of 100N what will be it's length when stretched by a load of 200N provided the elastic limit is not exceeded. Pls I need d solutions and steps to solve this problem now it is my assignment to be submitted tomorrow
stretches 5 cm for 100 N
so
stretches 10 cm for 200 N
so
25 + 10 = 35 cm
Stretch = 30-25 = 5 cm.

Length = 25 + (200N/100N) * 5cm = 25 + 10 = 35 cm.
