A charged paint is spread in a very thin uniform layer over the surface of a plastic sphere of diameter 12.0 cm, giving it a charge of -35 u.
(a) Find the electric field at the surface of the sphere just outside the paint layer.
(b) Find the electric field at 5.00 cm outside the surface of the paint layer.
Select one:
E = 6.50 x 107 N/C, E = 2.60 x 107N/C
E = 1.50 x 107 N/C, E = 1.20 x 10°N/C
E = 0.03 x 10' N/C, E = 0.23 x 10°N/C
None of these is correct
E = 8.74 x 107N/C, E = 5.40 x 10' N/C
E = 8.74 x 10' N/C, E = 2.60 x 10' N/C
E = 6.50 x 10N/C, E = 5.40 x 10?N/C

True or false graphs must include scales that increase by the same amount

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
