Dear Student,
Please find below the solution to the asked query:
The situation is as shown in the figure below.
Given that the reading is 10 kg, when spring is vertical. So,
Kx=10 kgwt
Where x is the extension in the spring.
If the block is displaced horizontally as in the diagram, the restoring force on the spring is,
Reading=Kx'=K(
x
cos θ
)=K(
x
cos 60
)
=K(
x
1
2
/
)
⇒Reading=2(Kx)=20 kgwt
Hope this information will clear your doubts about the topic.
