Question

Weight of a matter in air 5N and in water 3N.what is the weight of matter in that liquid of specific gravity 0.8?

Answer 1

Weight in air is 5N
Acceleration due to gravity is 10m/s^2

we need to find the mass of that object...

weight = mass × g
so, mass = weight\ g
that is, 5N\ 10
= 1\2
0.5 Kg.

Weight of matter in liquid of specific gravity of 0.8 m/s^2

weight= mass× g
0.5× 0.8
0.4 N
0.4N in liquid.

i hope this will help you.
thanks
