If the density of a liquid increases, the upthrust will ____

Every liquid exerts an upward force on the objects immersed in it. The upward force is called ________.

The mass of a planet is double and its radius is half compared to that of earth. Assuming $$g=10m/s^2$$ on earth, the acceleration due to gravity at the planet will be :

A spring balance measures the weight of an object in air to be $$0.1 N$$. It shows a reading of $$0.08 N$$ when the object is completely immersed in water. If the value of acceleration due to gravity is $$10 {m}/{{s}^{2}}$$, the volume of the object is

Acceleration due to gravity on moon is $$0.166$$ times than that on the earth. A man weighing $$60$$kg on earth would weigh __________kg on moon.

'G' represents
I. Acceleration due to gravity.
II. Weight
III. Gravitational constant
Which combination is correct?

High tides at antipodes are caused due to.

On doubling the distance between two masses the gravitational force between them will:

A body dropped from a certain height attains the same velocity as another falling with an initial velocity u from a height h below the first body. Which one of the following gives the correct expression for the square of the initial velocity of the second body $$(u)$$? (g is the acceleration due to gravity).
