What is the escape speed of the Sun ?

Text Solution

AI Generated Solution

To find the escape speed of the Sun, we can follow these steps: ### Step 1: Understand Escape Speed Escape speed is the minimum speed needed for an object to break free from the gravitational attraction of a celestial body without any additional propulsion. ### Step 2: Use the Escape Speed Formula The formula for escape speed \( v_e \) from a celestial body is given by: \[ ...
