Which is the best example of newton's first law of motion? a small, lightweight ball and a large, heavy ball are dropped off the top of a very tall building. they both strike the ground at the same time. a basketball player shoots the ball from half court. it soars toward the basket until another player taps it making it go in a different direction. it takes you more effort to move a large box across the room than it does to move a small box across the room. you push your little sister on the swings at the park. you push harder and she ends up swinging higher.

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
