Question 1
The effect of rotation of the Earth on the value of acceleration due to gravity is
Question 2
Assuming earth to be a sphere of mass M and radius R, the acceleration due to gravity g is proportional to:
Question 3
An object is thrown from the surface of a planet with speed vertically upward then maximum height reached by particle will be
Question 4
The change in the value of g at a height ‘h’ above the surface of the earth is the same as at a depth ‘d’ below the surface of earth. When both ‘d’ and ‘h’ are much smaller than the radius of earth, then which one of the following is correct?
Question 5
The time period of an earth satellite in circular orbit is independent of
Question 6
A satellite is revolving in fixed circular orbit around earth and making four revolutions in a day. If earth start contracting and its radius becomes half of the present radius then the satellite will make how many revolutions in a day?
