NEET 2025 Physics spring based question MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Two identical point masses P and Q, suspended from two separate massless springs of spring constants k₁ and k₂, respectively, oscillate vertically. If their maximum speeds are the same, the ratio (A₀Q/A₀P) of the amplitude A₀Q of mass Q to the amplitude A₀P of mass P is:
A
k₂/k₁
B
k₁/k₂
C
√(k₂/k₁)
D
√(k₁/k₂)
Correct Answer
Option D
Detailed Explanation
The maximum speed in SHM is given by v_max = Aω, where ω = √(k/m). Since v_max is the same, A₀Q√(k₂) = A₀P√(k₁), leading to A₀Q/A₀P = √(k₁/k₂).
