Question

A spring 20cm long is stretched to 25cm by a load of 50N. What will be its length when stretched by 100N assuming that the elastic limit is not reached? I want the answer abd solving to this question and also the formula for young modulus of elasticity

Answer 1

stretched by twice the load? has to be twice as long, 50cm.

spring constant=young'sModulus*Area/Length

Y=k*length/area

Answer 2

I think bob meant twice the stretch. 30cm

Answer 3

1.25N

Answer 4
