* Relative density of Bob =ρ * Time period in water = ? Mg text eff =σ vg -ρ w ⋅ vg =(σ-ρ w ) ⋅ vg σ ⋅ v ⋅ g texteff =(σ-ρ w ) ⋅ vg ⇒ g text eff =((σ-ρ w /σ)) ⋅ g =((ρ-1/ρ)) ⋅ g Time period T '=2 π ⋅ √(1/ g ) T '=2 π ⋅ √(1/ g ) ⋅(( p / p -1)) = T ⋅ √(( p / p -1)) T ' = T ⋅ √( p / p -1)

Q. The metallic bob o fa simple pendulum has the relative density $ρ$ . The time period of this pendulum is T. If the metallic bob is immersed in water, then the new time period is given by.

$T (\frac{ρ - 1}{ρ})$

$T (\frac{ρ}{ρ - 1})$

$T \frac{ρ - 1}{ρ}$

$(T \frac{ρ}{ρ - 1})$

Q. The metallic bob o fa simple pendulum has the relative density ρ. The time period of this pendulum is T. If the metallic bob is immersed in water, then the new time period is given by.

T(ρρ−1​)

T(ρ−1ρ​)

Tρρ−1​​

(Tρ−1ρ​​)

Q. The metallic bob o fa simple pendulum has the relative density $ρ$ . The time period of this pendulum is T. If the metallic bob is immersed in water, then the new time period is given by.

$T (\frac{ρ - 1}{ρ})$

$T (\frac{ρ}{ρ - 1})$

$T \frac{ρ - 1}{ρ}$

$(T \frac{ρ}{ρ - 1})$
