Two masses are 10 kg and 20 kg, separated by 2 m. The gravitational force between them is (G is universal constant):

The state of a body when the net force acting on it is zero and it is falling under gravity is called:

What is the mass of an object whose weight is 49 N on Earth? (g = 9.8 m/s²)

Atmospheric pressure at sea level is approximately:

When a body is partially or fully immersed in a fluid, it experiences an upward force equal to the weight of the fluid displaced. This is:

Calculate the pressure exerted by a column of water 10 m high. (Density of water = 1000 kg/m³, g = 10 m/s²)

The value of 'g' at the poles is:

Momentum of a body of mass 5 kg moving with 10 m/s is:

Which of the following describes 'free fall'?

If a body floats in water with half its volume submerged, its density is:

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:
