The time ** of a spring-mass system is T in air when the mass is partially immersed in water the time ** of oscillation is
(A) T (B) < T (C) >T (D) ≤ T
Correct option (B) < T
Explanation:
The time ** of the spring mass system in air = T = 2p√(m/k) When the mass is immersed in water partially, the buoyent force = ρAxg & the spring force = k.x. when the body is displaced through a small distance x.
