Question

a body whose volume is 100 cm cube weighs 10 Newton in air find its weight in water take G is equal to 10 metre per second square density of water is equal to 1000 kg per metre cube​

Answer 1

Answer:

9.9 kg

Explanation:

Volume=100cm^3=100/100^3 m^3

weight=10 N

mass=1 kg

Density of object=1/100/100^3 kg/m^3

=100000 kg/m^3

So object's Relative Density=Density/Density of water

=100000/1000=100

But Relative Density is also=Mass in Air/loss of mass in water

So,100=1/loss of mass

loss of mass=1/100 kg

Mass in water=actual mass-loss

=1-1/100

Mass=0.99 kg

Weight=9.9 kg
