Force

If the distance between two masses is reduced to one-third, the gravitational force becomes:

Which of the following follows the law of floatation?

The ratio of gravitational force on the moon to that on Earth for the same mass is:

Relative density of a substance is 0.8. Will it float or sink in water?

If a body is weightless in space, it means:

A force of 10 N acts on a body of mass 2 kg for 3 seconds. The change in momentum is:

If the mass of a planet is 4 times Earth and its radius is 2 times Earth, 'g' on that planet is:

A person can jump higher on the moon than on Earth because:

If the Earth stops rotating, the value of 'g' at the equator will:

A block of ice is floating in water. When the ice melts, the water level:

The velocity of a falling object in a vacuum depends on:

The center of gravity of a uniform rod is at:

What is the unit of the Universal Gravitational Constant G?

When a body is thrown upwards, the work done by gravity is:

Newton's third law of motion applies to:

The pressure exerted by a 76 cm column of mercury is called:

If the mass of Earth is 6 x 10^24 kg and its radius is 6.4 x 10^6 m, find 'g'.

A syringe works on the principle of:

The force of gravitation between two bodies does NOT depend on:
