Answer» ANSWER: (ii) The center of gravity of a uniform half meter RULE is 25 cm. The rule balances HORIZONTALLY on a knife edge at 29 cm mark when a weight of 20 kgf is suspended from one end. The difference in the center of gravity and the point of balance=29−25=4cm(Y) The weight is suspended at one of the EXTREMES, Let us assume at the 50 cm end. Therefore, the distance from the point of knife edge to the weight =50−29=21cm(X) Weight of meter rule = Y X × Suspended weight ∴ Weight of meter rule = 4 21 ×20=105 kgf solution

Answer»

ANSWER:

(ii) The center of gravity of a uniform half meter RULE is 25 cm.

The rule balances HORIZONTALLY on a knife edge at 29 cm mark when a weight of 20 kgf is suspended from one end.

The difference in the center of gravity and the point of balance=29−25=4cm(Y)

The weight is suspended at one of the EXTREMES,

Let us assume at the 50 cm end.

Therefore, the distance from the point of knife edge to the weight =50−29=21cm(X)

Weight of meter rule =

× Suspended weight

∴ Weight of meter rule =

×20=105 kgf
