`Y_(g) and Y_(r)` denotes the Young's modulus of glass and rubber respectively. Glass is more elastic than rubber hence ..........

A

`Y_(g) =Y_(r)`

B

`Y_(g) lt Y_(r)`

C

`Y_(g) gt Y_(r)`

D

`(Y _(g))/(Y_(r)) =0`

Text Solution

Verified by Experts

The correct Answer is:
C
`("stress")/("strain")=K,` elastic modulus and `("stress")/("strain")=Y` Young modulus
`therefore Y=K`
`therefore K _(g) gt K _(r) implies Y_(g) gt Y_(r)`
