Answer:
Elastic potential energy E = 0.5 J
Step-by-step explanation:
Let us assume we have to find the elastic potential energy stored in the spring.
Given: k = 100
change in the length of the spring x = 0.2-0.1 = 0.1 m
Elastic potential energy
E =
plugging the values we get
Hence, Elastic potential energy E = 0.5 J
