Question

Two identical spring-mass systems, one kept horizontally & another vertically , the natural frequency for the horizontal system is vertical system. $\left(\mathrm{in}\mathrm{absence}\mathrm{of}\mathrm{gravity}\right)$

• A. equal to
• B. greater than
• C. less than

Answer 1

The correct option is A equal to

Natural frequency is only dependent on mass and stiffness of the spring. As both the systems are having identical masses and springs attached, so the natural frequency will not be affected by the orientation of the system.
