Post Utme Pan Atlantic University 2020 Physics Objective / Multiple Choice
Question 14 POST_UTME_PAN-ATLANTIC_UNIVERSITY • 2020 • PHYSICS • objective

A block of mass ( m ) is attached to a horizontal spring with a spring cons\tant ( k ). The block is displaced by a dis\tance ( x ) from its equilibrium position and released from rest. The block's motion is described by the equation ( x(t) = A \cos(omega t) ), where \( omega = \sqrt{\frac{k}{m}} \). If the spring cons\tant is doubled, what is the new angular frequency?

Answer Options

A. \( \sqrt{\frac{k}{m}} \)
B. \( \sqrt{\frac{2k}{m}} \)
Correct Answer C. \( \sqrt{\frac{4k}{m}} \)
D. \( \sqrt{\frac{8k}{m}} \)
Correct Answer
C
Correct Option:
\( \sqrt{\frac{4k}{m}} \)
