$($text H$8)$: An incense burner is attached to a small ring. The ring is supported by two strings. One string is altached to the ceiling. The other string passes over an ideal pulley $($i$.$e$.$ it is light and has frictionless$)$ and carries a $1\mathrm{.}00kg$ mass at its free end. To do this question you will need TWO FBDs $...$one for the main ring and one for the mass. Think about the $3$rd law.

$($a$)$ Calculate the magnitude of the three forces acting on the ring. $($Ans: one rope is

$12.$aN$,$ other rope $15\mathrm{.}81$N and weight of bumer is $13\mathrm{.}4N)$

$($b$)$ Calculate the mass of the incense burner. $($Ans: $1\mathrm{.}37kg)$

Haplut hint This is a tough one. The first thing to hole is that you will need $2$ FBD$\text{'}$sll One for the $1\mathrm{.}00kg$ mass and one for the ring. The $1kg$ mass FBD can be used to figure out the tension in the string holding it$.$ Due to Nowton's grit Law, that tension is the same tension in the $60$ rope holding on to the right side of the ring. So start with the FBD for the $1kg$ mass and find the Tension in the string. Then use that value for the tension in the rightmost string when doing the $FBD$ of the ring.
