A piece of iron of density `7.8xx10^(3)"kg m"^(-3)` and volume `100 "cm"^(3)` is totally immersed in water . Calculate (a) the weight of the iron piece in air (b) the upthrust and (c ) apparent weight in water .

Text Solution

AI Generated Solution

To solve the problem step by step, we will calculate the weight of the iron piece in air, the upthrust when it is immersed in water, and finally the apparent weight of the iron piece in water. ### Step 1: Calculate the Weight of the Iron Piece in Air **Formula:** The weight of an object can be calculated using the formula: \[ W = m \cdot g \] where \( W \) is the weight, \( m \) is the mass, and \( g \) is the acceleration due to gravity. ...
