x=0.15 m, F= 30 N
Since, F= -kx
=> -k = 30/0.15
=> k = -200 N/m
1) Since, T= pi/4
Since, T = 2 x pi x sqrt(m/-k)
=>pi/4= 2 x pi x sqrt(m/200)
=> m = 3.125 kg
2) Since, Its length increases by 3 cm
Therefore, New length(x) = 15+3 =18 cm
Since, F= -kx(where x is the change in displacement)
=> F = 200 x 18/100
=>F = 36 N
