If P represents radiations pressure, c represents speed of light and Q represents radiation energy striking a unit area per second, the non-zero integers x,y and z such that is dimensionless, are
View answer and explanation
Correct option: B
Option B () is correct because it involves finding the values of x, y, and z such that is dimensionless, where P is radiation pressure, c is the speed of light, and Q is radiation energy striking a unit area per second. By equating the dimensions to M0L0T0, we can solve for x, y, and z.
