Block with m = 300 grams oscillates at the end of a linear spring with k = 6.5 n/m. (assume this is a top-down view and the block is sliding on a frinctionless surface; neglect gravity)
a) what is the period of the block's motion in seconds
b) if the blovk's max acceleration is 2 m/s^2, what is the amplitude of the motion (m)

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?
