Question

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))`

Answer 1

Correct Answer - 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.
