If P represents radiation pressure, C represents speed of light and Q represents radiation energy striking a unit area per second, then the non-zero integers x, y and z such that Px Qy Cz is dimensionless are :
Answer & explanation
Correct answer: option 2
M0L0T0 = PxQyCz
= [ML-1T-2]x [ML2T-2]y [LT-1]z
x + y = 0 ⇒ x = -y
-x + 2y + z = 0
-2x -2y - z = 0
x = -y
