A point charge q = -0.41 nC is fixed at the origin. Where must an electron be placed in order for the
electric force acting on it to be exactly opposite to its weight? (Let the y axis be vertical with the positive
direction pointing up.)

Which statements identify what astronomers currently know and think will happen with our universe? check all that apply. the big bang produced dark energy, which accounts for some of the energy needed to expand the universe. the vastness of space may contain a type of matter known as "dark matter." the universe is currently shrinking at a rapid rate. the universe is currently expanding at an accelerating rate. the big bang theory explains all the energy and matter discovered by scientists.
