Per NCERT §1.6.1 (key warning), a DIMENSIONALLY CORRECT equation is necessarily which?
ANot necessarily numerically correct
BAlways wrong by construction
CAlways trivial and useless
DAlways numerically correct anyway
Answer & Solution
Correct answer: A. Not necessarily numerically correct
NCERT §1.6.1: dimensional consistency is necessary but not sufficient. K = (3/16)mv² passes the check but is numerically wrong.
