Dust particles released by comets are continuously acted upon by sun s radiation pressure in radial outward direction Assuming a dust particle with p 3 5 x 10 kg m and reflection coefficient 0 for what value of radius r does gravitational force on dust particle just balance the radiation force on it from sunlight power radiated by sun 4 x 1026 w mass of sun 2 x 1030 kg
