Suppose you are standing on the center of a merry-go-roundthat is at rest. you are holding a spinning bicycle wheel over yourhead so that its rotation axis is pointing upward. the wheel isrotating counterclockwise when observed from above. for this problem, neglect any air resistance or frictionbetween the merry-go-round and its foundation. q.suppose you now grab the edge of thewheel with your hand, stopping it from spinning. what happens to themerry-go-round? it remainsat rest. it begins torotate counterclockwise (as observed from above).it begins torotate clockwise (as observed from above).

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?
