Question

Imagine a satellite of the Sun in a circular orbit around the Sun, midway between the sun and the earth.Then

• A. The period of the satellite is nearly $129$ days
• B. The period of the satellite is nearly $183$ days
• C. The acceleration of the satellite is twice the acceleration of the Earth
• D. The acceleration of the satellite is four times the acceleration of the Earth

Answer 1

The correct option is A The period of the satellite is nearly $129$ days

We know that $T^2\propto r^3$
Thus we get
$\frac{365}{x}=(2{)}^{3/2}$
or
$x=129days$
