Homework Help: Problem in physic of electric charge

  1. Jan 18, 2009 #1
    consider a circular clock face of radius= 50cm.a charge of 3nC is placed at the 3 o'clockpoint (a distane of 50cm from the center of the face). a charge of 6nC is placed at the 6 o'clockpoint.9nC is placed at the 9 o'clockpoint and 12nC is placed at the 12 o'clockpoint.
    what is the electric field in the centre of the clock
