If P represents radiation pressure, c represents speed of light and Q represents radiation energy striking a unit area per second, then non-zero integers x,y and z such that PxQyCz is dimensionless, are
By substituting the dimension of given quantities
[ML−1T−2]x[MT−3]y[LT−1]z=[MLT]0
By comparing the power of M,L,T in both sides x + y = 0 .....(i)
-x + z = 0 ......(ii)
-2x - 3y - z = 0 ......(iii)
The only values of x,y,z satisfying ((i),(ii) and (iii) corresponds to (b).
