Victoria’s ambition is to climb Mount Everest, also known in Nepal as Sagarmatha and in Tibet as Chomolungma. She thinks that the effect of the changing gravitational force will mean that she will find the climb easier as she climbs higher. The Earth’s radius is approximately 6400 km. The height of mount Everest is approximately 8.8 km. a. Explain how the gravitational force between two objects changes with the distance between them. b. With reference to the data above and to what you know about gravitational force field, evaluate Victoria’s prediction. c. Calculate the height above the Earth’s surface at which Victoria’s weight would be half its value on the surface

When these objects moves away or come close together the change occurs in force of gravity.

Explanation:

When these objects moves away or come close together the gravitational force between two objects changes with the distance between them . At the center of the earth gravitational force is the highest while moving away from the center, the force of gravity decreases. Yes, Victoria’s prediction was right about gravitational force. When we go to a specific height, the force of gravity decreases because we know that gravitational force decreases with increasing height. Victoria’s weight would be half its value on the surface when she is present at the altitude of 2642 km because at that altitude force of gravity is also half.

0.11 m/s and 0.28 m/s should be correct
