Question

Two particles of the same mass m are moving in circular orbits because of force, given by $F\left( r \right) = {{ - 16} \over r} - {r^3}$

The first particle is at a distance r = 1, and the second, at r = 4. The best estimate for the ratio of kinetic energies of the first and the second particle is closest to :

$6 \times {10^{ - 2}}$

$3 \times {10^{ - 3}}$

${10^{ - 1}}$

$6 \times {10^{ 2}}$
