A 2.00 g air-inflated balloon is given an excess negative charge, q1 = -3.00 × 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 d = 6.80 cm to make the balloon float. Assume the balloon and rod to be point charges. The Coulomb force constant is 1/(4xe0) = 8.99 × 10° N-m²/C² and the acceleration due to gravity is g = 9.81 m/s². In order for this to occur, what polarity of charge must the rod possess? 92 is positive 92 is negative 92 is a proton 92 is neutral How much charge q, does the rod have? 92 = C

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
