Question

escape velocity at surface of planet mercury has been found to be 4.3 km/sec and value of g is 3.78 m/sec over there . find the radius of planet ​

Answer 1

Answer:

2.445*10^6 m

Explanation:

Ve = (2gR)^0.5

Ve = 4.3 km = 4.3 * 10 ^3 given

and g = 3.78 m/s^2 given

So, putting all the values we get R = 2.445*10^6 m
