Question

The dimensional formula of the product of two physical quantities P and Q is ML2T–2. The

dimensional formula of P/Q is ML0T–2. Then what are the units of physical quantities P and Q.

a) Newton and meter b) kg and meter

c) second and meter d) Newton and second​

Answer 1

Answer:

a) Newton and meter

Explanation:

$dimensional formula \\Newton(force) = ML{T}^{ - 2} \\meter = L$

$\frac{Newton(force)}{meter} = \frac{ML{T}^{ - 2} }{L} \\ ML^{0} {T}^{ - 2}$
