`IgtIIgtIIIgtIV`

C

`IgtIVgtIIgtIII`

D

`IIIgtIVgtIgtII`

Text Solution

Verified by Experts

The correct Answer is:
C
(c) `U=-vecM.vecB=-MBcos theta`
In case I: `theta=180^@, U=+-MB`
In case II: `theta=90^@, U=0`
In case III: `theta` is acute, `U=-ve`
In case IV: `theta` is obtuse, `U=+ve`
`:. IgtIVgtIIgtIII`
