Acharge q1=4.00 mc is located at the origin of a coordinate system. another charge q2=4.60 mc is located at x=-1.10 m and y=-3.80 m, and another q3=4.10 mc is located at x=-3.50 m and y=1.30 m. calculate the magnitude of the net electric force on the charge q1 in newtons (n).

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?

Use the illustration to describe how the electromagnetic spectrum changes as its frequency moves from radio waves to higher energy gamma waves in terms of wavelength and amplitude.
