A 1-kg rock is suspended by a massless string from one end of a
1 answer:
Answer:
The weight of measuring stick is 9.8 N
Explanation:
given information:
the mass of the rock, = 1 kg
measuring stick, x =1 m
d = 0.25 m
to find the weight of measuring stick, we can use the following equation:
τ = Fd
τ = 0
-
= 0
F_{r} = the force of the rock
F_{s} = the force of measuring stick
= m g
= 1 kg x 9.8 m/s
= 9.8 N
thus, the weight of measuring stick is 9.8 N
