## Question - 3 : A train is moving with a speed of  72 km/h  on a curved railway line of 400 m radius. A spring balance loaded with a block of  5 kg is  suspended from the roof of the train. (i) What would be the reading of the balance ? (ii) If, in the above case, the spring makes an angle of 10 degree with the vertical, then what is the centripetal acceleration of the train ? ( g = 10 m/s^2, Tan 10 degree = 0.176 ).

## Sir i have a boubt that the centripetal force due to the ritatuon of earth is effecting the acceleration due to gravity , but the centripetal force is different for different masses , so the gravity is also different for diffrendi mass ? Help me.
