Answer:B

Explanation:

elastic constant(k)=80N/m

extension(e)=0.1m

Elastic potential energy=(k x e^2)/2

Elastic potential energy=(80 x (0.1)^2)/2

Elastic potential energy=(80x0.1x0.1)/2

Elastic potential energy=0.8/2

Elastic potential energy=0.4

Elastic potential energy is 0.4 joules

Answer:

0.4 j just tried it and it worked!
