A planet in a distant solar system is 10 times more massive than the earth and its radius is 10 times smaller. Given that the escape velocity from the earth is 11 km `s^(-1)` , the escape velocity from the surface of the planet would be `x xx 11` km/s. Find x.

Verified by Experts

`A=3xx10^(-2)m,V=340 ms^(-1), lambda=2m`
`:.` The incident wave towards right is given by `y=A"sin"(2pi)/(lambda)(vt-x)=3xx10^(-2)sin pi(340t-x)`
The reflection at the rigid wall will produce a phase difference of `pi`.
`:.` The reflected wave is give by
`y=3xx10^(-2)sin(340 pit+pix+pi)`
`y=-3xx10^(-2) sinpi(340t+x)` towards left.
