Use the result of Question 45 (now with the sun instead of Earth as the center of force) to calculate the speed in m/s at which Earth revolves about the sun. Assume Earth’s orbit is nearly circular.
Speed of revolution of Earth around the Sun in m/s.
Answer to Problem 46A
Explanation of Solution
Given:
Earth’s orbit is circular.
Formula Used:
The velocity is given by,
Calculation:
As,
So, on substituting the values
Conclusion:
Therefore, the speed of revolution of Earth around the sun is
