MCQ
A physical quantity $P$ is given by $P= \frac{{{A^3}{B^{\frac{1}{2}}}}}{{{C^{ - 4}}{D^{\frac{3}{2}}}}}$. The quantity which brings in the maximum percentage error in $P$ is
  • A
    $A$
  • B
    $B$
  • $C$
  • D
    $D$

Answer

Correct option: C.
$C$
c
(c) Quantity $C$ has maximum power. So it brings maximum error in $P$.
