50 W/m2 energy density of sunlight is normally incident on the surface of a solar panel.  Some part of incident energy (25%) is reflected from the surface and the rest is absorbed.  The force exerted on 1m2 surface area will be close to (c=3 108 m/s):
(a)	20 10−8 N	(b)	35  10−8 N
(c)	15  10−8 N	(d)	10 10−8 N
