प्रश्न

State with reasons whether the sentence is  true or false .

 If the height of the orbit of a satellite increases, its velocity must also increase.

उत्तर

 The specific velocity with which the satellite revolves around a planet is known as critical velocity. It is given as 

\[v_c = \sqrt{\frac{GM}{R + h}}\]
So, we see that as the height (h) of the orbit of a satellite increases, it velocity must decrease. Hence, the statement is false.
