A hollow sphere of external radius R and thickness t A hollow sphere of external radius R and thickness t September 20, 2020 Category: Chapter 13 - Fluid Mechanics , MTG NEET Physics , Part 1 , Facebook Messenger WhatsApp Share this:TwitterFacebook Related Spheres of iron and lead having same mass are completely immersed in water. Density of lead is more than that of iron. Apparent loss of weight is W1 for iron sphere and W2 for lead sphere .Then W1/W2 isA solid sphere of radius R1 and volume charge density ρ=ρ0/r is enclosed by a hollow sphere of radius R2 with negative surface charge density σ, such that the total charge in the system is zero . ρ0 is positive constant and r is the distance from the centre of the sphere . The ratio R2/R1 isA cylindrical block floats vertically in a liquid of density ρ1 kept in a container such that the fraction of volume of the cylinder inside the liquid is x1. Then some amount of another immiscible liquid of density ρ2 (ρ2
