Question

If P is radiation pressure, C represents speed of light and Q is radiation energy striking a unit area per second, then non zero integers x, y and z such that P^xQ^yC^z is dimensionless are -

x = 1, y = 1, z = –1
x = 1, y = –1, z = 1
x = –1, y = 1, z = 1
x = 1, y = 1, z = 1

The correct answer is: x = 1, y = –1, z = 1
