Calculate the escape velocity of a satellite launched from the earth’s surface (Take g as 10ms-2 and the radius of the earth as 6.4 x 106m)
- 8.00 x 106ms-1
-
1.13 x104ms-1
- 3.58x102ms-1
- 5.59 x10-2ms-1
- 3.95x10-2ms-1
The correct answer is: B
Explanation
V = √2gr
= √2 x 10 x 6.4 x 106
1.13 x 104ms-1
