Does the escape speed of a body from the...

Does the escape speed of a body from the earth depend on (a) the mass of the body. (b) the location from where it is projected. © the direction of projection, (d) the height of the location from where the body is launched?

Text Solution

Verified by Experts

The escape speed `v_(es)=sqrt((2GM)/R)=sqrt(gR)`. Hence,
The escape speed of a body from the Earth does not depend on the mass of the body. (b) The escape speed does not depend on the location from where a body is projected. (c) The escape speed does not depend on the direction of projection of a body. (d) The escape speed of a body depends upon the height of the location from where the body is projected, because the escape velocity depends upon the gravitational potential at the point from which it is projected and this potential depends upon height also.
