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
विकल्प
T = `4π sqrt("m"(1/"k"_1 + 1/"k"_2))`
T = `2π sqrt("m"(1/"k"_1 + 1/"k"_2))`
T = `4π sqrt("m"("k"_1 + "k"_2))`
T = `2π sqrt("m"("k"_1 + "k"_2))`
उत्तर
T = `4π sqrt("m"(1/"k"_1 + 1/"k"_2))`
