1. Electrostatics

   • Force = q1q2 upon r square
   • Electric Field = q upon r sq.= f by q
   • Torque = p *E
   • Work Done to Deflect a Dipole = pE(cosa1 - cosa2 )
   • Potential Energy = -W
   • Flux = E.s
   • Gauss Law is field at any point on a closed surface due to all charges is 1 by epselon 0 times the charge enclosed by it .
   • Potential = q1q2 into (1 by r2 - 1 by r1)
   • dipole
     • End-on i.e. axial position
     • Broadside-on i.e. equatorial Position
