Question

Select the correct statement from the following and give reason

A) The orbital velocity of a satellite increases with the radius of the orbit
B) Escape velocity of a particle from the surface of the earth depends on the speed with which it is fired

Answer 1

option A child I think so because the reason is same as the first option

Answer 2

as i thinks both options are correct in their own sense
a) orbital velocity vary from radius
since
orbital velocity = root ( G × R)
b) the velocity required by the object to escape into space beyond the gravitational pull of earth called escape velocity so it depends on velocity with which it is fired or thrown
