An electric dipole is formed from ± 5.0 nc point charges spaced 3.0 mm apart. the dipole is centered at the origin, oriented along the y-axis. what is the electric field strength at point (x, y) = ( 20 mm ,0cm)? what is the electric field strength at point (x, y) = (0cm, 20 mm )?

Abaseball picther can throw a ball at about 90 miles per hour, v = 40 m/s, on solid rock ground. we now put him into space. when he throws the ball, which weighs mb = 0.15 kg moves away from himat the same speed. how long does it take the ball thrown in space to travel the 30 meters to the batter? he weighs mp = 100kg
