Question

An artificial satellite orbiting the earth does not the earth’s attraction
(a) is balanced by the attraction of the moon
(b) vanishes at such distances
(c) is balanced by the viscous drag produced by the atmosphere
(d) produces the necessary acceleration of its
motion in a curved path

Answer 1

Answer:

Explanation:

We observe weightlessness in satellite because the net magnitude of force on the body is almost zero i.e. earth's gravitation is nullified in terms of magnitude by centrifugal force. But, earth's gravitation is necessary to change the direction of satellite continously and thus providing the acceleration in terms of change in direction.
