Leia is presenting her project about gravity to her class. She says that both mass and distance affect how strong the gravitational force is, and that as the
distance between two objects increases, so does the gravitational force. Is Leia correct?
Yes, all of her statements are true.
No, because distance does not actually affect gravitational force.
No, because mass does not actually affect gravitational force.
No, because as distance increases, gravitational force decreases.

please help asap!!

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?
