Find the velocity of escape at the moon....

Find the velocity of escape at the moon. Given that its radius is `1.7xx10^(6)` m and the value of 'g' is `1.63 ms^(-2)`.

Text Solution

Verified by Experts

Given, `R = 1.7 xx 10^(6)m`
`g = 1.63 m//s^(2)`
`V = sqrt(2gR) = sqrt(2 xx 1.63 xx 1.7 xx 10^(6))`
`= 2.354 xx 10^(3) m//s`
