A vector `vecA` ur is rotated by a small angle `triangletheta` radian `(triangletheta ltl)` to get a new vector `barB` In that case `|vecB-vecA|` is:

A

`|vecA|Deltatheta`

B

`|vecB|Deltatheta-|vecA|`

C

`|vecA|(1-(Deltatheta^2)/2)`

D

0

Text Solution

Verified by Experts

The correct Answer is:
A
Arc length =radius x angle
So, `|vecB-vecA|=|vecA|Deltatheta`
