According to Newton`s 2nd law motion 
force = rate of change of momentum
        = mass× ( rate of change of velocity )
        = mass ×acceleration
       so the magnitude of the force acting on the body is
       ( 10×0.2 )N = 2 N

According to newton's second law of motion, Force = mass × acceleration Mass of given body = 10 kg Acceleration produced = 0.2 m/s^2 Therefore, Magnitude of force acting on the body = mass × acceleration =10 × 0.2 = 2 N
