A positively-charged balloon is brought near a neutral, conducting sphere (mounted on an insulating stand). The sphere is touched by a person and the balloon is moved away. Once the process is over, what is the charge on the balloon? What is the charge on the metal sphere?

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
