Q1. A point charge is distance from the center of the dipole consisting of charges separated by distance. The charge is located in the plane that bisects the dipole. At this instant, assume r>>s what is the magnitude of the force on dipole?
Q2. A package is dropped from a passing plane (moving in the horizantal direction) and produces a projectile motion as it is falling to the ground. If it takes the package only 32.12 seconds until it hits the ground, how far above the ground was the plane while the package was released? Overlook air resistance.
