Ameteoroid is moving towards a planet. it has mass m = 0.78×109 kg and speed v1 = 4.1×107 m/s at distance r1 = 2.8×107 m from the center of the planet. the radius of the planet is r = 0.26×107 m. the mass of the planet is m = 4.4×1025 kg. there is no air around the planet. calculate the value of pe1, in joules

Adisk with a radius of r is oriented with its normal unit vector at an angle q with respect to a uniform electric field. which of the following would result in an increase in the electric flux through the disk? check all that apply? a. increasing the area of the disk b. decreasing the given orientation angle of the disk c. decreasing the strength of the electric field d. increasing the given orientation angle of the disk, but not exceeding an angle of 90
