The systems shown in are in equilibrium if the spring balance is calibrated in newtons, what does it record in each case? `(g=10m//s^(2))`

Text Solution

Verified by Experts

The correct Answer is:
(a) `100N`
(b) `200N`
(c) `50 N`
`(a) "As "T=100N`
(b) `T=100N`
So, `2T=200N`
(c) `T=Mg sin 30^(@)`
`T=10xx10xx1/2=50N`
