Assuming the same current is running through two separate colls, why is it easier to thrust a magnet into a wire coil with one loop than one with four loops?
OA
because the electric field is stronger
OB.
because the magnetic field is stronger
OC. because the electric field is weaker
OD
because the magnetic field is weaker

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?
