Gravity is a conservative force. Which of the following is incorrect about this force?

The dimensional formula for gravitational constant is

Ball pens function on the principle of

At what height above the earth's surface does the acceleration due to gravity fall to 1% of its value at the earth's surface?

As we go from the equator to the poles, the value of g

The value of g at a particular point is 9.8 m/s². Suppose, the Earth suddenly shrinks uniformly to half its present size without losing any mass. The value of 'g' at the same point (assuming that the distance of the point from the centre of the Earth does not shrink) will now be

The acceleration due to earth`s gravity ______ when we go a little distance inside the earth. It ______ when we go a little distance above the earth.

An object is at a height R/2 above the Earth. What is the value of acceleration due to gravity at that instant?

The path of an object released from earth at a velocity less than escape velocity and more than orbital velocity is called

Escape velocity from earth is approximately

The escape velocity for a planet is v_e. A particle starts from rest at large distance from the planet and reaches the planet only under gravitational attraction. And then it passes through a smooth tunnel through its centre. Its speed at the centre of the planet will be

The time period of a pendulum is independent of the

Let v_o be the velocity of orbit around a planet. The escape velocity of the planet is

What is the orbital velocity of a satellite orbiting the earth just at the surface?

If a small part separates from an orbiting satellite, the part will

The path of a planet around the sun is elliptical as shown in the figure. Its velocity is greatest at

Compare the area swept by the line joining planet and sun at apogee (closest point in orbit) and perigee (farthest point in orbit) during a time interval `T`.

The radius of a planet's orbit increases by a factor of three. Correspondingly, time period becomes

The ratio of the inertial to gravitational mass is equal to

Which of the following statements is correct?
