A plane it parallel to the field. What it the magnitude of the gravitational field flux through the planar surface of area A? Let g be the magnitude of the uniform gravitational field. Answer in terms of g and A. The plane is tilted at 45 degree to the field. What is the magnitude of the gravitational field flux through the planar surface of areas A? 0 None of these The plane is horizontal. What is the magnitude of the gravitational field flux t through the planar surface of area A 0 None of these
Explanation / Answer
flux f = E.ds = EAcos? here f = gAcos? (1) If the plane is parallel to the gravitational field then the areal vector perpendicular is perpendicular to the field then ? = 900 f = gAcos900 = 0 answer is (2) (2) when ? = 450 f = gAcos450 = 1/v2gA answer is (3) (3) when ? = 00 f = gA answeris (3)
