Astudent's research indicates that Pluto's radius is 1.172 x 105 rn and its mass is 1.2 X1022 kg. Calculate the gravitational field strength at Pluto's surface. Input your two digit answer with no spaces or commas or periods. Check A student's research indicates that Pluto's radius is 1.172 x 10 m and its mass is 1.2 x 1022 kg. Calculate the force of gravity at Pluto's surface on an object with a mass of 100 kg. Input your two digit answer without spaces or commas. Answer: CheckAballoon with a radius ot 15 cm has an electric charge of 4.25 x 109 C Determine the electric field strength at a distance of 400 cm from the balloon's centre. Input your 3 digit answer without spaces or commas. Answer: Check Aballoon with a radius of 14 cm and an electric charge of 3.?5 x 109 C is brought within the electric eld ofthe larger balloon with the same charge so their centres are 400 cm apart. Determine the magnitude ofthe electric force exerted by this electric eld on the smaller balloon. You answer should be in the form abc x t'\" M. Input your 4 digit answer {abcd} without spaces or commas. Answer: Check Assume that the force of the gravitational field strength on the surface of Mars is 310' kag. An astronaut is standing on the surface of Mars. In his soacesuit he has a mass of 215 kg. What would his weight be at that location 1? Select one: ":3 A. 58.1 N E 854 N ":3 C. H36 N D 116 N Check Suppose two identical balloons are each positively charged and positioned with their centres far enough apart so they are not close to touching each other. The balloons are then moved farther apart so that the distance between their centres doubles. What would be the expected change in the force of repulsion of one balloon on the other due to their increased separation? Select one: O A. The magnitude of the force of repulsion decreases by a factor of 1/4 O B. The magnitude of the force of repulsion increases by a factor of 4 O C. The magnitude of the force of repulsion decreases by a factor of 1/2 O D. The magnitude of the force of repulsion increases by a factor of 2. Check
