Question

Radiation Pressure: Radiation from a star reaches a planets surface at an arrange rate of 2,700 w / m2.(Assume this is a single EM wave) Calculate the maximum value of E and B. Find the amount of momentum transferred to a perfect absorber. Assume the objects is a sphere of radius 30cm and a mass of 2kg. Find the force exerted on a roof that has dimensions 10cm x 20cm.
