$2\mathrm{.}12($extra bonus $5\%)$

A spherical particle of density $\backslash$rho $=5\mathrm{.}00(($g$))/($cm$^(2))$ and $2\mathrm{.}00-$mm radius is located at the same distance from

the Sun as the Earth. R$\_($SE$)=1\mathrm{.}5\backslash$times $10^(11)$m$.$

G$=6\mathrm{.}67\backslash$times $10^(-11)($Nm$^(2))/($kg$^(2))*$S$=1365(($W$))/($m$^(2))*$M$\_($S$)=1\mathrm{.}99\backslash$times $10^(30)$kg$.$ If the particle absorbs $100$

percent of the sunlight reaching it$,$ the ratio of the force exerted by the solar radiation to the force of

gravity exerted on the particle by the Sun is

a$.5\mathrm{.}8\backslash$times $10^(-5).$

b$.0\mathrm{.}58.$

c$.1\mathrm{.}0.$

d$.1\mathrm{.}7.$

e$.1\mathrm{.}7\backslash$times $10^(4).$
