1.) K = F/l
= 0.6* 9.8/2*10^(-2) = 2.94 * 10^2 N/m: Ans (D) : 294 N/m

2.) Ans (D) : Period

3.) Period = time/no. of oscillations
= 4/8 = 0.5 Sec : Ans (B)

4.) Amplitude of oscillation = displacement in the 0 velocity position
= 5/60 = 0.083 m: Ans (C)

5.) Frequency = (1/2*pi ) * sqrt(k/m) = 1/2pi sqrt(10/4)
= 0.25 Hz Ans(A)

6.) T = 2*pi *sqrt(l/g) => 2 = 2*pi * sqrt(l/9.8)
=> l = 1.0 m Ans (B)

7.) Ans (C) : acts ...
