A mass is suspended separately by two different springs in successive order, then the time period is T₁ and T₂ , respectively. If it is connected by both spring as shown in figure, then the time period T₀ , so the correct reaction is:
Options
- AT₀^2=T₁^2+T₂^2
- BT₀⁻²=T₁⁻²+T₂⁻²
- CT₀⁻¹= T ₁⁻¹+ T ₂⁻¹
- DT₀=T₁+T₂
Correct answer
B. T₀⁻²=T₁⁻²+T₂⁻²
Step-by-step solution
Time period of spring T=2 m ~K aligned & K=4 ^2 m T^2 & K 1 T^2 aligned For parallel combination of spring K=K₁+K₂ aligned & 1 T₀^2 = 1 T₁^2 + 1 T₂^2 & T₀⁻²=T₁⁻²+T₂⁻² aligned
