if p represents radiation pressure, c represent speed of light and Q represents radiation energy striking a unit area per second, then non-zero integers x,y and z such that `p^(x)Q^(y)c^(z)` is dimensionless are.

Options

A. `x = 1, y = 1, z = -1`
B. `x = 1, y = -1, z = 1`
C. `x = -1, y = 1, z = 1`
D. `x = 1, y = 1, z = 1`

Answer

b

Explanation

`P^(x)Q^(y)C^(z)` is dimensional when `[ML^(-1)T^(-2)]^(x) [ML^(2)T^(-2)//L^(2)T]^(y)[LT^(-1)]^(z) = M^(0)L^(0)T^(0)` solving ` x = 1`, y = 1, z = 1`.
