Define electric field. State whether it is a vector or a scalar quantity.

Prove that :Electric field intensity(E)= potential difference (V)/distance between two plates(d)i.e. E=V/d

V=W/q 

V=Fd/q 

V=F/q*d 

V=E.d [E=F/q] 

E=V/d

A charged particle carrying a charge 'q' moves in an electric field E. If its specific charge is 'S', write an expression of its acceleration in terms of the above entities.

A charge particle carrying a charge q moves in an electric field 'E'. If its specific charge is 'S', then force is given as

F = qE

and acceleration, a= F/m = SE ( since, q/m= S given )

acceleration, a = SE
