Solve the followi

Class 10th MHB - Science and Technology Part-1 10. Space Missions

Answer :

Mass of planet M = 8 x mass of earth = 8 x 6 x 10²⁴ kg

Radius of planet R = 2 x radius of earth = 2 x 6.4 x 10⁶ m

G = gravitational constant = 6.67 x 10^-11 N m²/kg²

So escape velocity = √

Escape velocity =

= 22.4 km/sec.

So escape velocity of the planet will be 22.4 km/sec
