# 21. Physics | Electrostatics | Electric Force on Charges in Electric Field | by Ashish Arora (GA)

0 Comment let us study the electric force on charges
in electric field. as we already discuss that electric field vector is defined as, force.
per unit positive charge. in electric field. a unit positive charge experiences a force
denoted by e vector. say in a region in electric field, e vector exist. so in this situation
i am drawing the direction of electric field in the region. and if i place a charge plus
q over here. so if e is the force on a unit positive charge the net force on the charge
q can be written as, f and it’ll be equal to q-e. and force on the positive charge will
be experienced in the direction of electric field only, in similarly if we place a charge
minus q in the region of electric field it experiences force f vector , which is q-e
vector in the direction opposite to the electric field but the magnitude is given by q-e only.
so always keep this note in your mind. for various application that , positives charges,
in electric field, experiences force. in the direction of electric field vector. and negative
charges. experiences a force . in direction. opposite to electric field vector , various
application will use the concept . although in definition of electric field we already
stated the same.
