Force

When an object is immersed in a liquid, its apparent weight is:

A hydrometer is used to measure:

Pascal's Law is valid for:

The force of gravitation between two bodies is F. If the mass of one body is doubled, the force becomes:

Which of the following describes the state of a body when the upthrust is equal to its weight?

If a body of mass 5kg is moved from the equator to the pole, its mass will:

The reason why we can't walk easily on a sandy beach is:

The density of air is approximately:

An object weighs 10N in air and 8N when fully immersed in water. The upthrust is:

If the radius of Earth was double its present value, and its mass remained the same, what would be the weight of a 60 kg person?

A hydraulic lift has pistons of radii 1cm and 10cm. What is the force multiplier?

Newton's Law of Gravitation is called universal because:

The center of gravity of a uniform ring lies:

Which of the following does not affect the value of g on Earth?

If a force of 5 N is applied on an area of 10 cm^2, the pressure is:

If the density of a body is equal to the density of the liquid:

A man can jump higher on the moon than on the earth because:

The product of mass and acceleration is:

What is the relationship between density (d), mass (m) and volume (v)?

When a body is dropped from a height, its potential energy is converted to:
