A vector has a magnitude x . If it is rotated by an angle `theta` then magnitude of change in vector is nx. Match the following two columns.
`{:(,"Column I ",,"Column II"),((A),theta=60^(@),(P),n=sqrt(3)),((B),theta=90^(@),(Q),n=1),((C), theta=120^(@),(r),n=sqrt(2)),((D), theta=180^(@),(s),n=2):}`

Text Solution

Verified by Experts

The correct Answer is:
A`to`q, B`to`r , C`to` p, D`to`s
(a)When `theta=60^@`

(b) When `theta=90^@`

( c)When `theta=120^@`
`therefore n=sqrt3`


(d)When `theta=180^@`
