A container of mass $M$ containing liquid of mass $m_0$ is kept on weighing machine. A ball of mass $m$ is released from rest from given position. Then choose correct option just after ball is released
  • AReading of weighing machine must be equal to $(M + m + m_0)g$
  • BReading of weighing machine $> (M + m + m_0)g$ only if density of ball $<$ density of liquid
  • CReading of weighing machine $> (M + m + m_0) g$ if density of ball $ \ne $ density of liquid
  • DReading of weighing machine $< (M + m + m_0)g$ if density of ball $ \ne $  density of liquid
