MCQ
A physical quantity is given by $X = {M^a}{L^b}{T^c}$. The percentage error in measurement of $M,L$ and $T$ are $\alpha ,\beta $ and $\gamma $ respectively. Then maximum percentage error in the quantity X is
  • ✓
    $a\alpha + b\beta + c\gamma $
  • B
    $a\alpha + b\beta - c\gamma $
  • C
    $\frac{a}{\alpha } + \frac{b}{\beta } + \frac{c}{\gamma }$
  • D
    None of these
✓

Answer

Correct option: A.
$a\alpha + b\beta + c\gamma $
a
(a) Percentage error in X $ = a\alpha + b\beta + c\gamma $
