The time period for small vertical oscillations of block of mass m when the masses of the pulleys are negligible and spring constant k1 and k2 is:
A. T = 4π\(\sqrt{m\left(\frac{1}{k_{1}}+\frac{1}{k_{2}}\right)}\)
B. T = 2π\(\sqrt{m\left(\frac{1}{k_{1}}+\frac{1}{k_{2}}\right)}\)
C. T = 4π\(\sqrt{m\left(k_{1}+k_{2}\right)}\)
D. T = 2π\(\sqrt{m\left(k_{1}+k_{2}\right)}\)
