Chapter 13, Problem 13A
What is the value of Earth’s gravitational field at the center of Earth?
Expert Solution & Answer
To determine
The value of Earth’s gravitational field at the center of Earth.
Answer to Problem 13A
Zero
Explanation of Solution
Introduction:
The region surrounding the Earth in which the other particles experience a force of attraction towards the Earth is called Earth’s gravitational field. The gravitational field is a vector quantity and is directed towards the center of the earth. The gravitational field will become smaller as the particles move farther away from the Earth.
The gravity is produced only by the attraction to the mass of a particle. Once the particle approaches the center of Earth, it experiences more attractive force from all sides of the Earth. When the particle really reach the actual center of Earth, it experiences nearly same attractive force from all sides of the earth. Hence they cancel each other and the mean gravitational field becomes zero.

- Taking a Hike A hiker begins a trip by first walking 21.0 km southeast from her car. She stops and sets up her tent for the night. On the second day, she walks 46.0 km in a direction 60.0° north of east, at which point she discovers a forest ranger's tower. y (km) Can N W-DE 45.0° 60.0° Tent Tower B x (km) ☹ (a) Determine the components of the hiker's displacement for each day. SOLUTION Conceptualize We conceptualize the problem by drawing a sketch as in the figure. If we denote the displacement vectors on the first and second days by A and B, respectively, and use the ---Select-- as the origin of coordinates, we obtain the vectors shown in the figure. The sketch allows us to estimate the resultant vector as shown. Categorize Drawing the resultant R, we can now categorize this problem as one we've solved before: --Select-- of two vectors.
