4. The sun has a mass of Mo=2.0 x 1030 kg and it radiates P = 3.8 x 1026 W in the form of electromagnetic radiation. The gravitational constant is G = 6.7 x 10-11 N- (a) Find expressions for the gravitational and electromagnetic forces on a sphere of radius r which is located a distance R from the center of the sun, assuming that all of the electromagnetic radiation incident on the sphere is absorbed, and that the sphere is composed of material with a density of p=5 g/cm³. (b) For what value of r are these forces equal? I would like for you to calculate the actual number for this part. 44°F Search Sunny TAB CAPS LOCK E 3 L % S T བ ༥ ཇ་ཥ ་ F 9 YUEOPL K CTRL SHIFT NVIDIA GEFORCE RTX N ALT x C B m BACKSPACE 5:44 PM 3/24/2024 DELETE PGON
