A mass m is allowed to fall on a pedestal fixed on the top of a vertical spring. If the height of the mass was H from the pedestal and the compression of the spring is d then the spring’s force factor is given by
\[\begin{array}{c} \sum_{n}^{\infty} \\ \frac{1}{4} \end{array}\]
\[\begin{array}{c} \sum_{n}^{\infty} \\ \frac{1}{4} \end{array}\]
- \(M g \frac{(H+d)}{d^{2}}\)
- \(2 M g \frac{(H-d)}{d^{2}}\)
- \(\frac{M g}{2} \frac{H}{d^{2}}\)
- \(2 M g \frac{(H+d)}{d^{2}}\)
Answer
(D) 2 M g (H+d) d^ 2
