Two uniformly charged, infinite, nonconducting planes are parallel to a yz plane and positioned at x 50 cm and x 50 cm. The charge densities on the planes are 50 nC/m2 and 25 nC/m2 , respectively. What is the magnitude of the potential difference between the origin and the point on the x axis at x 80 cm

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

As the distance from a magnet increases, what happens to the magnet force?

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?
