Question

A satellite of mass '$m$', moving around the earth in a circular orbit of radius $R$, has angular momentum $L$. The areal velocity of satellite is :

• A. $L/2m$
• B. $L/m$
• C. $2L/m$
• D. $2L/m_e$

Answer 1

The correct option is A $L/2m$

According to kepler's second law, areal velocity is constant .
i.e. $A_v=\frac{rv}{2}=\frac{\omega r^2}{2}=\frac{L}{2m}$
