Question

A body of density d , is counterpoised by M g of weight of density d 2 in air of density d . Then, the true mass of the body is, M, M 1 - d d 2, M 1 - d d 1, M 1 - d d 2 1 - d d 1

MARKS App · Accepted Answer

Let the M 1 is the mass of the body. Apparent weight of the body in air = Apparent weight of standard weight in air ∴ Actual weight - Upthrust due to displaced air ⇒ M 1 g - M 1 d 1 d g = M g - M d 2 d g M 1 g 1 - d d 1 = M g 1 - d d 2 ∴ M 1 = M 1 - d d 2 1 - d d 1
