Concept explainers
The magnitude and direction of the gravitational force exerted on one sphere by the other three.
Answer to Problem 42P
Solution:
The net force acting on one sphereis
Explanation of Solution
Given:
Mass of each sphere = 7.5 kg
The side of the square=0.80 m
Formula Used:
The expression for the of gravitational attraction
Here
Calculation:
With the help of equation
Where d is the side of the square, m is the, mass of the sphere.
Diagonal =
Substitute for
With the help of equation
Since
Substitute
Conclusion:
Therefore, the net force acting on one sphereis
