The pressure at the bottom of a pond is 2 atmospheres. If the depth is doubled, the pressure (neglecting atmosphere) will:

What is the acceleration of a 5 kg mass acted upon by a 20 N force?

If an astronaut moves from Earth to the Moon, his:

Pascal's Law is applicable for:

What force is required to produce an acceleration of 9.8 m/s² in a body of mass 1 kg?

A man of weight 600 N on earth will weigh how much on the moon? (g_moon = 1/6 g_earth)

Why are the foundations of high-rise buildings made wide?

A balloon filled with helium rises in the air because:

The ratio of the SI unit to the CGS unit of force is:

If the density of an object is less than the density of the liquid, the object:

What is the effect of force on a rigid body?

Pressure in a liquid at the same horizontal level is:

An iron nail sinks in water but an iron ship floats because:

If the Earth's radius decreases by 1% while mass remains same, the value of 'g' will:

A body of mass 100g is moving with a velocity of 5m/s. Its momentum is:

The gravitational force between two bodies is F. If the mass of one body is doubled and distance is halved, the new force is:

At what depth from the surface of Earth does the value of 'g' become half of its surface value? (R is Earth radius)

A piece of wood floats in water with 1/4th of its volume above the surface. The density of wood is:

If the escape velocity on Earth is 11.2 km/s, what would it be on a planet with double the mass and double the radius of Earth?

A body is thrown vertically upwards. At the highest point:
