In the previous question, if `R` and `S` are interchanged, balanced point is shifted by

A

`30 cm`

B

`40/3 cm`

C

`100/3cm`

D

`20 cm`

Text Solution

Verified by Experts

The correct Answer is:
C
If `R` and `S` wave interchanged,
`{:(l=75,100-l=25):}`
Balance point will be shifited by `5-25=50cm`
