Class 11 Gravitation Worksheet

According to Newton's Universal Law of Gravitation, the force of attraction between two point masses is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. What is the unit of the Universal Gravitational Constant (G)?

The acceleration due to gravity (g) at a height 'h' above the Earth's surface decreases. If R is the radius of the Earth, for small values of 'h' compared to R, the approximate formula for g at height h is:

Kepler's second law states that the line joining a planet to the sun sweeps out equal areas in equal intervals of ____.

Which of the following statements is true about the gravitational force?

Define gravitational potential energy. What is its value at infinite distance from a mass?

The escape velocity from the surface of the Earth depends on:

For an object revolving in a circular orbit around a planet, the necessary centripetal force is provided by the ____ force.

If the radius of the Earth suddenly shrinks to half its present value without any change in its mass, what will be the new acceleration due to gravity (g') at the surface compared to the original 'g'?

A geostationary satellite revolves around the Earth in a ______ orbit.

Why does a body weigh more at the poles than at the equator?
