A spring balance and a physical balance are kept in a lift. In these balance equal masses are placed. If now the lift starts moving upward with constant acceleration, then.A. The reading of spring balance will increases increses and the equilibrium position of the physical balance will disturbB. The reading of spring balance will remain in unchanged and physical balance will remain in equilibriumC. The reading of spring balance will decrease and physical balance will remain in equilibriumD. The reading of spring balance will increases and the physical balance will ramain in equilibrium |

Answer» Correct Answer - D The friction force will act downwards. So the reading of spring balance will increase. In case of physical balance, the fictitious force will act on both the pans, so the equilibrium is not affected. |
