Question: a 000230kilogram air inflated balloon is given an excess negative...

Question details

A 0.00230-kilogram air inflated balloon is given an excess negative charge, q1--3.25 x 108 C, by rubbing it with a blanket. It is found that a charged rod can be held above the balloon at a distance of d 0.0600 m to make the balloon float. In order for this to occur, what polarity of charge must the rod possess? How much charge, q2, does the rod have? Assume the balloon and rod to be point charges. The Coulomb force constant is M4πεο)-8998 109 N. m2/C2 and the acceleration due to gravity g-9.81 m/s2 O positive O negative O proton O neutral 72 is Number 42T
