Fill in the blank and explain the statement with reasoning:

 If the height of the orbit of a satellite from the earth surface is increased, the tangential velocity of the satellite will ...... 

Fill in the Blanks

Solution

 If the height of the orbit of a satellite from the earth surface is increased, the tangential velocity of the satellite will decrease.
Explanation: This can be easily inferred from the formula of critical or tangential velocity.

\[v_c = \sqrt{\frac{GM}{R + h}}\]
