Answer» The force ACTING on a charged particle in the presence of an ELECTRIC field is given by: F=qEF=qE, where:F is the forceq is the magnitude of the CHARGEE is the electric fieldThe force acts in the same direction as that of the electric field, when the charge is positive and the opposite direction when the charge is negative.The weight of a body acts downwards and is given by:W=mgW=mg, where:W is the weightm is the mass of the bodyg is the acceleration due to gravity |
