Question

The dimensions of $\frac{a}{b}$ in the equation P = $\frac{a–t^{2}}{bx}$where P is pressure, x is distance and t is time are-

• A. [M²LT^–3]
• B. [MT^–2]
• C. [ML³T^–1]
• D. [LT^–3]

Answer 1

Answer: (B)

$MT^–2$

Answer 2

$\left\lbrack \frac{a}{b} \right\rbrack$ = [P][x]

= ML^–1T^–2L = MT^–1
