Two identical objects,each with a mass M,are attached to each other via a spring with a spring constant k.The two objects are oscillating such that one is always moving in the opposite direction and with the same speed as the other.If the spring were replaced with a stiffer spring having a spring constant equal to 2k,and the objects were replaced with objects having a mass of 2M,the period of oscillation would
A)remain the same.
B)increase.
C)decrease.

The period of oscillation for a system of two masses connected by a spring is given by T = 2π√(M/k). If both the spring constant and the mass are doubled, the period remains the same because the ratio M/k does not change.
