Answer:
Linear charge density (I) = Q/2πR
Explanation:
Linear charge density (I) = charge (Q) per unit length(L)
I = Q/L
For a thin ring of charge with radius R, the length will be equal to the circumference of a circle.
Circumference of a circle = 2πR
Then, the length of the thin ring of charge is 2πR
Linear charge density (I) = Q/2πR
Therefore, for a thin ring of charge of radius R, which lies in the x-y plane and is centered on the z-axis. The linear charge density, l, of the loop is given by Q/2πR

Assuming the liquid to be water ,
the density
of water is :
Buoyant force exerted by a liquid on an object with
of it's volume immersed is :

where ,
is the buoyant force
is the density of the liquid
is the acceleration due to gravity
Thus at equilibrium:

from these , we get the density of brass to be 
which is not possible
