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. What would happen to the scale reading if the lift is moving upward with (i) constant velocity (ii) constant acceleratioin
