A body of density D1 and mass M is moving downward in glycerine of density `D_2`. What is the viscous force acting on it ?

A

`Mg(1-(D_(2))/(D_(1)))`

B

`Mg(1-(D_(1))/(D_(2)))`

C

`MgD_(1)`

D

`MgD_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
Time period of simple pendulum.
`T=2pisqrt((l)/(g_("eff"))) " Here",g_("eff")=(g^(2)+(W^(2))/(m^(2)C^(2)))^(1/2)`
