Unit of  Force = 1 N
unit of  Work done = J' = 10 J
unit of  Time :  T = 1 second.

unit of Mass :  M' = ?

Work done = Force * Displacement
1 J = 1 N * 1 meter
1 J' = 1 N  *  new-meter  = 10 J
=>  Unit of displacement and length = new-meter = 10 meters.
========
Force = Mass * Length / Time²

1 N = new-kg * new-meter / sec²
1 N =  new-kg * 10 meter/ sec²
but 1 N = 1 kg * 1 meter/sec²

=>  new-kg = 1/10 = 10⁻¹  kg   = 0.1 kg
