A rocket is launched normal to the surface of the earth, away from the sun, along the line joining the sun and the earth. The sun is 3 × 10^5 times heavier than the earth and is at a distance 2.5 × 10^4 times larger than the radius of the earth. the escape velocity from earth’s gravitational field is ue = 11.2 m/s. The minimum initial velocity (ue) = 11.2 m/s. the minimum initial velocity (us) required for the rocket to be able to leave the sun-earth system is closest to (Ignore the rotation of the earth and the presence of any other planet

A planet of radius R = 1/10×( radius of Earth ) has the same mass density as Earth. Scientists dig a well of depth R/5 on it and lower a wire of the same length and a linear mass density 10^−3 kg m(_1) into it. If the wire is not touching anywhere, the force applied at the top of the wire by a person holding it inplace is (take the radius of Earth = 6 × 10^6 m and the acceleration due to gravity on Earth is 10 m/s^2
