Particle 0 experiences a repulsion from particle 1 and an attraction toward particle 2. For certain values of d1d1d_1 and d2d2d_2, the repulsion and attraction should balance each other, resulting in no net force. For what ratio d1/d2d1/d2 is there no net force on particle 0?

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?

Which two particles are found in the center of an atom

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
