Pseudo force is an imaginary force which is recognised only by a non-inertial observer to explain the physical situation according to newton’s laws. Magnitude of pseudo force Fp is equal to the product of the mass m of the object and the acceleration a of the frame of reference. The direction of the force is opposite to the direction of acceleration, F_(p)=-ma spring weighing machine inside a stationary lift reads 50 kg when a man stand on it.
