In circular motion, which of the following relations are valid ?

A

`overset rarr(upsilon) = overset rarr(omega) xx overset rarr(r )`

B

`overset rarr(a_(t)) = overset rarr(alpha) xx overset rarr(r )`

C

`overset rarr(a_(t)) = overset rarr(omega) xx overset rarr(r )`

D

`overset rarr(a) = overset rarr(omega) xx overset rarr(a_(t))`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`overset rarr(upsilon) = overset rarr(omega) xx overset rarr(r ), overset rarr(a_(t)) = overset rarr(alpha) xx overset rarr_(r ), overset rarr(a_(r)) = overset rarr(omega) xx overset rarr_(r )`
These are valid relations, but `overset rarr(alpha) = overset rarr(omega) xx overset rarr(a_(t)` is not valid.
