Centre of Gravity

The point through which the whole weight of the body acts is called

• Inertial Point

• Center of gravity

• Centriod

• Central point

Center of gravity is usually located where

• more weight is concentrated

• less weight is concentrated

• less mass is concentrated

• more mass is concentrated

Center of gravity of an object depends on it's

• weight

• mass

• density

• shape

Where will be the centre of gravity of a uniform rod lies ?

• At its end

• At its middle point

• At its centre of its cross sectional area

• Depends upon its material

Where the center of gravity of a circle lies?

• At its centre

• Anywhere on its radius

• Anywhere on its circumference

• Anywhere on its diameter

A simple method to find centre of gravity of a body is usage of

• stop watch

• plumbline

• pendulum

• gauge

What is one way you might increase the stability of an object?

• Lower the center of gravity

• Raise the center of gravity

• Increase the height of the object

• Shorten the base of the object

Where do you hang the plumb line when determining the CG?

• It doesn't matter, because it always goes through the CG

• Only from the corners

• From the point where you are suspending the object

• At the right angle

If we suspend lamina at different positions, its center of gravity will still lie along the

• Plumb line

• Line of force

• Line of weight

• Gravity line

There are three kinds of equilibrium, which of following is odd one out?

• Stable equilibrium

• Metastable equilibrium

• Unstable equilibrium

• Neutral equilibrium
