A) (Uniform Field) Flash Gordon has a mass of 80 kg and is standing on the surface of a planet of mass 6.00 x 1024 kg with a radius of 7000 km. Determine the gravitational force field strength *g". Determine the constant acceleration of Flash Gordon if he falls "a". B) (Uniform Field) Barbarella places a 10 mg pithball of charge -250 uC between two massive parallel places separated by 50 cm with a potential difference of 10 000 V. The force of gravity is negligible relative to the electric force. Determine the electric force field strength 'S'. Determine the ball's constant acceleration "a'. C) (Point Source Field) Commander Adama is initially 63 800 km from the centre of the Earth and he falls towards the Earth for a long period of time until he is rescued by space rangers where he is only 12 760 km from the centre of the Earth. Determine the gravitational force field strength "g' and instantaneous acceleration "aint' at both positions. The Earth masses 5.98x1024 kg. D) (Point Source Field) Captain Archer has a mass of 100 kg and he wears an electric suit of charge +1 mC and floats near a space station of charge - 5 C. He is initially 100 m from the space station and after some period of time he ends up at a distance of 10 m from the space station. Determine the electric force field strength 'S' and instantaneous acceleration "alinst" at both positions. E) (Point Source Field) Commander Sinclair is on the Earth standing 10 m below a 115 kV DC power line with 1000 A of current running North. A 10 mg pithball of charge -250 JC if fired underneath and the power line at a speed of 1 000 m/'s from Commander Sinclair' position. Determine the magnetic force field strength 'B' and the instantaneous acceleration "dinst" for instantaneous velocity directions of I) [North], II) [North 30" East], III) [Northeast], IV) [North 60 East], V) [East]
