Q. No.The effective spring constant in calculating the time period of SHM of the system of springs and the block is:
1. \((k_1+k_2)\)
2. \(|k_1-k_2|\)
3. \(\Big(\frac{1}{k_1}+\frac{1}{k_2}\Big)^{-1}\)
4. \(\Big|\frac{1}{k_1}-\frac{1}{k_2}\Big|^{-1}\)
1. \((k_1+k_2)\)
2. \(|k_1-k_2|\)
3. \(\Big(\frac{1}{k_1}+\frac{1}{k_2}\Big)^{-1}\)
4. \(\Big|\frac{1}{k_1}-\frac{1}{k_2}\Big|^{-1}\)
