Q.	The weight of a body acts through the centre of –
A.	gravity
B.	mass
C.	both (1) and (2)
D.	buoyancy
Answer» A. gravity
Explanation: The centre of gravity of a collection of masses is the point where all the weight of the object can be considered to be concentrated. The entire weight acts through the center of gravity instead of acting through the individual masses. In a uniform gravitational field (like the field close to the surface of theEarth) the Centres of Gravity and Mass are in exactly the same place.
