The escape velocity of a body on the earth surface is $11.2 km / s$ . If the same body is projected upward with velocity $22.4 km / s$ , the velocity of this body at infinite distance from the centre of the earth will be

Options:

Answer:

Solution:

$V^{'2} = V^{2} - V e^{2} V^{'} = V^{2} - V e^{2} = (22.4)^{2} - (11.2)^{2} V^{'} = 11.2 3 km / s$
