हिन्दीGiven below are two statements regarding a block oscillating on an ideal spring of constant \( k \): Statement I: The dimensional formula of the ratio \( k/m \) is \( [\text{T}^{-2}] \). Statement II: The speed of the block is maximum when it is at the equilibrium position (\( x = 0 \)). In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 1
Both Statement I and Statement II are correct.
Explanation
\( [k] = [\text{M T}^{-2}] \implies [k/m] = [\text{T}^{-2}] \), so Statement I is correct. At \( x = 0 \), spring potential energy is zero and all mechanical energy is kinetic, so speed is maximum, making Statement II correct.
