1This is called radial but it can be taken as linear
wrong!
PG-102 EXAMPLE 7.3
FOLLOWING THINGS ARE WRONG IN IT-
1.HOW CAN WE CALCULATE LINEAR ACCELERATION WHEN THE PARTICLE IS MOVING WITH UNIFORM SPEED.
2.THEY USED FORMULA LINEAR ACCELERATION=v2/r [4]
WHICH IS THE FORMULA FOR RADIAL ACCELERATION.
NOTE:NO DISREGARD FOR BOOK,AUTHOR OR PUBLISHERS INTENDED.
I JUST AM GUESSING AND POSTING IT FOR CONFIRMATION.I MAY BE WRONG

11See john your concept is wrong.
See it is said that the speed is uniform but moves in a circle .
In a circle The direction of the velocity changes.
Therefore there is acceleration and that acceleration is v2/r and This is called radial but it can be taken as linear.
See the velocity of the particle is linear rite and change in linear is linear acceleration and this change is brought about by radial acceleration and therefore the example is rite
Got it ?
1read#1 carefully.
bhai kahin maine kaha ki radial acceleration nahi hoga!!!!!
i m just talking about the question in problem.
what is linear acceleration!!!!!!
got it?
BTW read the last line also(NOTE written in #1).[NO DISREGARD.........].
1this misunderstanding on ur part is understandable
but please note that linear accleration has been said for acceleration that is not angular
hence there is nothing wrong there
you will rarely find a mistake in HCV seriously if you are uncomfortable with something
the odds are that u are at fault !!
1@philip
one thing i must make perfectly clear i never say nething with that much sureity if i myself m not sure.
this misunderstanding on ur part is not understandable to me.
tell me one thing how many types of accelerations r there.
2 only na-tangential(linear) and angular(radial).
now check ur line
linear accleration has been said for acceleration that is not angular
hence there is nothing wrong there

you are right
but the thing is that radial and linear axis are not in IIT JEE syllabus as such ..
but your understanding is correct
I havent seen the book but if what you are saying is true then the author seems to have made a small mistake..
