In the oscillation of a spring – block system on a smooth horizontal surface, match the entries of column I with the entries of column – II.
Column−IColumn−II(a) If mass of the block is doubled(P) Energy of oscillation becomes four times(b) If amplitude of oscillation is doubled(Q) Maximum speed of particle become 2 times(c) If force constant is doubled(R) Time period becomes √2 times(d) If angular frequency is doubled(S) Potential energy at extreme position becomes 2 times
