Two identical brass balls mounted on wooden posts initially have different amounts of charge, one +5 μC, and the other +19 μC. The balls are allowed to touch and then are separated again. What is the final charge on each ball?
A 2.15 g air‑inflated balloon is given an excess negative charge, ?1=−3.50×10−8 C,, by rubbing it with a blanket. It is found that a charged rod can be held above the balloon at a distance of ?=7.20 cm to make the balloon float. Assume the balloon and rod to be point charges. The Coulomb force constant is 1/(4??0)=8.99×109 N⋅m2/C2 and the acceleration due to gravity is ?=9.81 m/s2.
In order for this to occur, what polarity of charge must the rod possess?
?2 is a proton
?2 is positive
?2 is negative
?2 is neutral
How much charge ?2 does the rod have?
?2= C
