Question 14 POST_UTME_ABU • 2020 • PHYSICS • objective

A block of mass $m$ is placed on a frictionless surface and attached to a horizontal spring with spring cons\tant $k$. The block is displaced by a dis\tance $x$ and released from rest. The resulting simple harmonic motion has a period $T = 2\pi\sqrt{\frac{m}{k}}$. If the mass of the block is doubled and the spring cons\tant is halved, what is the new period?

A. 2\pi\sqrt{\frac{m}{2k}}

B. 2\pi\sqrt{\frac{2m}{k}}

Correct Answer C. 2\pi\sqrt{\frac{m}{k/2}}

D. 2\pi\sqrt{\frac{2m}{2k}}

Correct Answer

Correct Option:

2\pi\sqrt{\frac{m}{k/2}}
