Definition: Electric Field  = F E q ο =  A vector  Exists before  test charge is introduced  Is produced by other  charges (not  q 0 )   q 0 is small so as to not disturb the charges  producing the  field  it is a mathematical construct Units :  N/C Force on tiny “test charge” q 0 charge q 0

Example: Calculate  the force on an alpha particle  (q = +2e)  if it is placed in the  field. q [ ] = C N E 1000 Repeat for an electron.
