Answer is B.
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
