Solution

The correct option is B $54 g$
Weight of the wood $= 5 \times 0.8 = 4 g m$
$∴$ Total weight of beaker $= 50 + 4 = 54 g m$

A beaker is partly filled with water, the beaker and the contents have a mass of 50gm. A piece of wood having a volume of 5c.c. is floated in the beaker. The density of wood is 0.8g/c.c. The mass of the beaker and its contents is:

The correct option is B 54gWeight of the wood =5×0.8=4 gm∴ Total weight of beaker =50+4=54 gm
