F_B cos 60°=Mg  ⇒F_B =((Mg)/(cos 60°))  F_A =F_B sin 60°=Mg tan 60°
$${F}_{{B}} \mathrm{cos}\:\mathrm{60}°={Mg} \\ $$$$\Rightarrow{F}_{{B}} =\frac{{Mg}}{\mathrm{cos}\:\mathrm{60}°} \\ $$$${F}_{{A}} ={F}_{{B}} \mathrm{sin}\:\mathrm{60}°={Mg}\:\mathrm{tan}\:\mathrm{60}° \\ $$

Thanks sir, i appreciate.  Should i put   Mg  =  500N  ???  And are we not using the radius sir?
