A spring with spring constant k, has an extension x, when a mass m, is attached to it. Another spring identical to the first is hung parallel to the first and the same mass m is hung across both. Which option gives the correct values of extension and spring constant of the combination?
- (A)Extension:
x/2; Spring constant:k/2 - (B)Extension:
x/2; Spring constant:2k - (C)Extension:
2x; Spring constant:k/2 - (D)Extension:
2x; Spring constant:2k
