Show, with the aid of a sketch, how the electric potential varies in the space cl positive point charge, and ii) close to a negative point charge. ose to i) a sketch also how the electric potential energy of both a positive charge and a negative charge varies as a function of distance from i) a positive point charge and i) a negative point charge. how how the electric potential close to a point charge can be obtained from coulomb's law (b) to recharge a 12-v battery, a battery charger must move 3.6 x 10% c of charge from the negative to the positive terminal. what amount of work is done by the battery charger? how many kilowatt hours is this? (c) how much electrical charge is needed to raise an isolated metal sphere of radius 1.0 m to a potential of 1 .0 106 v? (d) what is the resistance of 1,000 m of 4-mm diameter copper wire? (the resistivity of copper, pou 1.7 x 10-8 ω m)

After a big snowfall, you take your favorite rocket-powered sled out to a wide field. the field is 195 m across, and you know that your sled accelerates at a rate of 3.65 m/s2 when the rocket is on. how much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time?
