Can you please explain the following question: A body floats in water with 2/3rd of its volume inside water. What is the the relative density ?

Dear student,
 
The mass of the body = mass of water it displaces 
V = volume of body
Ρ = density of water
.. then mass of water displaced M = (2/3V x Ρ) kg

Density of body = M/V = (2/3VP)V = 2/3Ρ.. the body has a density 2/3 that of water - 

.. it's relative density is 2/3 (relative to water)
 
 
Hope this helps.
Thankyou

A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
