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 1 m² surface area will be close to (c = 3 × 10⁸ m/s)(A) 15 × 10⁻⁸ N(B) 35 × 10⁻⁸ N(C) 10 × 10⁻⁸ N(D) 20 × 10⁻⁸ N |
