Question 38 POST_UTME_OAU • 2018 • PHYSICS • objective

A particle of mass $m$ is moving in a circular orbit of radius $r$ under the influence of a central force $F(r) = \frac{k}{r^2}$. If the particle has an initial velocity $v_0$ at $r = r_0$, calculate the total energy $E$ of the particle.

Answer Options

Correct Answer A. \frac{1}{2} m v_0^2 - \frac{k}{r_0}
B. \frac{1}{2} m v_0^2 + \frac{k}{r_0}
C. \frac{1}{2} m v_0^2 - \frac{k}{r}
D. \frac{1}{2} m v_0^2 + \frac{k}{r}
Correct Answer
A
Correct Option:
\frac{1}{2} m v_0^2 - \frac{k}{r_0}
