a simple pendulum us making oscillations with it's bob immersed in a liquid of density 1/n times of bob? whta is it's time period.?​

Answer»

Answer:

2πlng−−−√

2πl(1−1N)g−−−−−−−−√

2πlng−−−√

2πl(n−1)g−−−−−−−−√

Answer :

B

Solution :

As DISCUSSED in THEORY part

T=2πlg(1−ρσ)−−−−−−−−√

ρ=density of liquid

σ=density of BOB material

Given ρ=σn

hence PERIOD is 2πl1−(1n)g−−−−−−−−√
