Question

If a heavenly object like an asteroid or a planetoid revolving around the sun moves into an orbit of smaller radius, its speed increases.

• A. True
• B. False

Answer 1

The correct option is A True

Speed of asteroid or a planetoid revolving around the sun is given by $V=\sqrt{\frac{G{M}_s}{R_o}}$

So speed of a satellite depends on $\frac{1}{\sqrt{R_o}}$

So if radius is reduced then velocity will be increased.

so the given statement is true.
